Abstract
This is the first in a series of papers in which we describe and report the analysis of a large survey of Herbig Ae/Be stars in circular spectropolarimetry. Using the ESPaDOnS and Narval high-resolution spectropolarimeters at the Canada–France–Hawaii and Bernard Lyot Telescopes, respectively, we have acquired 132 circularly polarized spectra of 70 Herbig Ae/Be stars and Herbig candidates. The large majority of these spectra are characterized by a resolving power of about 65 000, and a spectral coverage from about 3700 Å to 1 μm. The peak signal-to-noise ratio per CCD pixel ranges from below 100 (for the faintest targets) to over 1000 (for the brightest). The observations were acquired with the primary aim of searching for magnetic fields in these objects. However, our spectra are suitable for a variety of other important measurements, including rotational properties, variability, binarity, chemical abundances, circumstellar environment conditions and structure, etc. In this paper, we describe the sample selection, the observations and their reduction, and the measurements that will comprise the basis of much of our following analysis. We describe the determination of fundamental parameters for each target. We detail the least-squares deconvolution (LSD) that we have applied to each of our spectra, including the selection, editing and tuning of the LSD line masks. We describe the fitting of the LSD Stokes I profiles using a multicomponent model that yields the rotationally broadened photospheric profile (providing the projected rotational velocity and radial velocity for each observation) as well as circumstellar emission and absorption components. Finally, we diagnose the longitudinal Zeeman effect via the measured circular polarization, and report the longitudinal magnetic field and Stokes V Zeeman signature detection probability. As an appendix, we provide a detailed review of each star observed.
INTRODUCTION
Herbig (1960) was the first to perform a systematic study of a certain class of stars that we call now Herbig Ae/Be (HAeBe) stars, and whose observational parameters are as follows:
the spectral type is A or earlier, with emission lines;
the star lies in an obscured region of space;
the star illuminates fairly bright nebulosity in its immediate vicinity.
Herbig selected these characteristics following the observational properties of the lower mass counterparts of HAeBe stars – T Tauri stars – and built a list of 26 HAeBe stars satisfying these criteria. This list, as well as the Herbig characteristics, have been extended since this original study (e.g. Herbig & Bell 1988; Thé, de Winter & Perez 1994; Vieira et al. 2003), and we now know of more than a hundred HAeBe stars of spectral type earlier than F5. All of them do not necessarily show all Herbig characteristics, but all of them have infrared (IR) excess with an abnormal extinction law (compared to classical Be stars).
The characteristics enumerated above suggest that HAeBe stars are very young, still surrounded by dust and gas in an envelope or disc. However, it was the spectroscopic study of Ström et al. (1972) that brought the first solid evidence that Herbig Ae/Be stars are in the pre-main-sequence (PMS) phase of quasi-static contraction, by showing that their surface gravities are systematically lower than those of their main-sequence (MS) counterparts. Herbig Ae/Be stars are therefore generally believed to be the evolutionary progenitors of MS intermediate-mass (A/B) stars.
Before the work of Palla & Stahler in the early 1990s, intermediate-mass stars with masses above 3 M⊙ were believed to not experience a PMS phase similar to that of lower mass stars (Larson 1972). More detailed calculations performed by Palla & Stahler (1990, 1991, 1992, 1993), including deuterium burning during the protostellar collapse and the PMS phase, show that optically visible PMS stars could be observed, up to masses of about 8 M⊙. There calculations considered a constant mass accretion rate during the protostellar collapse, and from the upper envelope of the distribution of Herbig Ae/Be stars in the Hertzsprung–Russell (HR) diagram, they concluded that all stars with masses lower than 8 M⊙ are formed with a similar mass accretion rate of the order of 10−5 M⊙ yr−1.
However, following this work, many Herbig Be stars with masses larger than 8 M⊙ have been discovered in the field of the Galaxy (see e.g. Fig. 4 of this paper), as well as in very young clusters (e.g. Martayan et al. 2008), implying that the simplified model of Palla & Stahler – with a constant mass accretion rate at all masses – may be insufficient to explain the observations. In fact, Palla & Stahler themselves proposed that the mass accretion rate should be time dependent. Norberg & Maeder (2000, hereafter NM00), and then Behrend & Maeder (2001, hereafter BM01), proposed that the mass accretion rate depends on the mass or the luminosity of the growing star. As a result, the mass accretion rate should increase while the star is growing and gaining in mass and luminosity, until the circumstellar (CS) matter becomes sufficiently rare and the massive accretion phase stops. Whereas a unique accretion rate of 10−5 M⊙ yr−1 as proposed by Palla & Stahler (1993) results in a maximum PMS star mass of around 8 M⊙, a modulated mass accretion rate, as proposed by NM00 and BM01, allows the birthline to reach the zero-age main sequence (ZAMS) at much higher masses (above 20 M⊙).
Herbig Ae/Be stars are indeed observed with masses as large as 20 M⊙, with a distribution more concentrated between 1.5 and 3 M⊙ (see Table 2 and Fig. 4 of this paper). Their spectral types are found between F5 and B2 (Vieira et al. 2003), and many of them show some spectroscopic and photometric activity, reflective of their young age. Many types of activity can be found among Herbig Ae/Be stars, but their origins are not well understood. Among them we find the UX Ori stars, with the Herbig Ae star UX Ori as the prototype. These stars are characterized by a very strong photometric variability (up to 3 mag in the V band), and by the presence of transient absorption features in their spectra that may be due to episodic accretion events (e.g. Mora et al. 2002). While some authors think that these characteristics are created by the infall of cometary bodies on to the star (e.g. Grady et al. 2000b), others are more convinced by the theory of accretion from a disc, whether via the intermediary of a magnetic field, or not (Natta, Grinin & Tambovtseva 2000; Mora et al. 2004). The presence of winds is detected in many HAeBe stars through P Cygni profiles observed in Hα and sometimes in metallic and He lines (e.g. Finkenzeller & Mundt 1984; Bouret, Catala & Simon 1997; Bouret & Catala 1998). Some authors have proposed that these winds have a stellar origin (e.g. Böhm & Catala 1994), while others believe that a disc wind is present (e.g. Corcoran & Ray 1998; Vieira et al. 2003). However, strong variability in Hα emission profiles is observed in a few HAeBe stars, some of them at times showing double-peaked profiles, and sometimes P Cygni profiles (e.g. Thé et al. 1985a; Catala et al. 1986a). These stars show periodic cyclical modulations not only of their Hα emission, but also of metallic lines such as the ultraviolet (UV) Mg ii h&k doublet (e.g. Catala et al. 1989), as well as of their X-ray emission (e.g. Testa et al. 2008). Their spectra also show UV emission lines of highly ionized species such as N v and O vi (e.g. Bouret et al. 1997). Bouret et al. (1997) proposed that these characteristics are due to the presence of a non-axisymmetric wind controlled by a stellar magnetic field. Various non-photospheric spectral features, in addition to those discussed above, are observed in the spectra of HAeBe stars, some with variability and others without. However, the interpretation of each one of these features, as well as their diversity, is not understood at all. The fact that HAeBe stars cover such a large range of mass, temperatures, age and evolutionary state, as well as the fact that these stars evolve at a variety of rates, certainly must be connected with the large variety of observed HAeBe activity phenomena and our difficulties to interpret them.
HAeBe stars are important astrophysical objects because they represent the late formative stages of intermediate-mass stars. They are therefore significant for understanding general and specific phenomena involved in star formation. Moreover, HAeBe stars can help us to understand a number of perplexing properties of their MS descendants, in particular chemical peculiarities, very slow rotation and magnetic fields, observed individually or in combination in a significant fraction of MS A/B stars.
Among the MS A/B stars, a significant fraction shows photospheric abundance anomalies (as compared to solar abundances, and to the abundances of the majority of MS A/B stars). These anomalies are believed to result from atomic diffusion within their surface layers due to the competition between radiative levitation and gravitational settling (e.g. Michaud 1970). One important condition necessary to allow this phenomenon to occur is the absence of strong deep mixing in those layers, which would tend to overwhelm these separation processes. As rotation-driven circulation is an important source of such mixing, this condition implies that such chemically peculiar stars should be slow rotators. It has been observed that nearly all chemically peculiar Am, Ap/Bp and HgMn stars are characterized by slow rotation (rotation periods longer than ∼1 d) compared to the ‘normal’ (non-peculiar) A/B stars (Abt & Morrell 1995). The origin of this slow rotation is not well understood. In the case of Am and HgMn stars, slow rotation might be the result of tidal interaction occurring in close binary systems (i.e. those with orbital periods shorter than 100 d; e.g. Abt 2009). The mechanism responsible for the slow rotation of Ap/Bp stars is likely related to their strong magnetic fields. Stępień (2000) discussed different theories aimed at explaining this slow rotation, and he concluded that magnetic braking must occur during the PMS phase in order to reproduce the rotational angular momenta of MS A/B stars. Stepien demonstrated that magnetic coupling of a PMS star with its accretion disc would slow the rotation of the star and increase its rotation period to a few days. In order to produce the slowest rotators – those with observed rotation periods greater than about one month – the disc must disappear sufficiently early during the PMS phase to allow strong magnetized winds to carry away a large quantity of angular momentum before the star reaches the ZAMS.
Until recently we had very few observational constraints on the magnetic fields and the rotation of Herbig Ae/Be stars. To our knowledge, only two thorough observational studies of the evolution of the angular momentum of intermediate-mass stars during the PMS phase have been undertaken. Böhm & Catala (1995) concluded that if these stars rotate as solid bodies, the evolution of the angular momentum must depend on stellar mass, while if the internal rotation varies as (radius)−2, the observations of HAeBe and MS A/B stars in young clusters are consistent with conservation of total angular momentum at all masses. Wolff, Strom & Hillenbrand (2004) concluded that PMS intermediate-mass stars lose angular momentum before they start the PMS phase, while angular momentum is conserved during the radiative phase of PMS evolution. Both of these analyses provided very interesting results that should be discussed in the framework of a scenario of angular momentum evolution that includes magnetic fields.
A number of studies have been attempted to detect magnetic fields in Herbig Ae/Be stars, without much success (e.g. Catala et al. 1993; Hubrig, Schöller & Yudin 2004). Apart from a marginal detection in HD 104237 reported by Donati et al. (1997), and a possible detection in HD 101412 proposed by Wade et al. (2007) (both being now firmly confirmed magnetic stars: Alecian et al., in preparation), no other convincing magnetic detections have been reported before the present survey. The reason is likely limited precision and an insufficiently large stellar sample as a consequence of limited observational capabilities. Fortunately, many of these limitations are overcome by today's spectropolarimetric facilities: telescopes with large collecting area, high-efficiency instruments, large spectral range and high spectral resolution.
In order to thoroughly investigate magnetism and rotation in HAeBe stars, we have performed a large survey of 70 stars using the newest high-resolution spectropolarimetric instruments: ESPaDOnS [at the Canada–France–Hawaii Telescope (CFHT), USA] and Narval (at the Télescope Bernard Lyot, TBL, France). Within the context of this survey we have detected a small number of new magnetic stars and confirmed the presence of a magnetic field already discovered during a parallel ESPaDOnS programme focused on massive stars in Orion (LP Ori; Petit et al. 2008). Those discoveries (HD 190073, HD 200775, HD 72106, V380 Ori and LP Ori), and the analysis we performed to characterize their magnetic fields and related properties, have already or will be described in other papers (Wade et al. 2005; Catala et al. 2007; Alecian et al. 2008a; Folsom et al. 2008; Petit et al. 2008; Alecian et al. 2009b; Petit et al., in preparation). While this survey is focusing on HAeBe stars in the field of the Galaxy, we have also performed a similar survey of HAeBe stars in three young clusters and detected three more magnetic stars: NGC 6611 601, NGC 2244 201 and NGC 2264 83 (Alecian et al. 2008b, 2009a). The description of this cluster survey will be presented in an upcoming paper (Alecian et al., in preparation).
We are now publishing a series of papers describing the complete sample of observed field stars, discussing the observations and their analysis (this paper, which is Paper I of the series), an analysis of their rotation velocities (Alecian et al. 2013, hereafter Paper II), an analysis of their magnetic properties (Wade et al., in preparation, hereafter Paper III), and the characterization of the CS contributions to the spectra of the sample (Alecian et al., in preparation, hereafter Paper IV).
This paper is organized as follows. In Section 2 we review the sample selection, and in Section 3 the observational procedure and data reduction, and summarize the characteristics and quality of the reduced spectra. In Section 4 we determine fundamental parameters for the stars of the sample, and in Section 5 we describe the extraction and fitting of the least-squares deconvolution (LSD) profiles that we use for the majority of our analysis. In Section 6 we discuss the magnetic field diagnosis carried out in a number of different ways. Section 7 provides a discussion of the results and conclusions relevant to the analysis to be reported in Papers II, III and IV.
SAMPLE SELECTION
Our study required the selection of a relatively large number of HAeBe stars to allow us to derive statistically meaningful conclusions about the presence of magnetic fields in these stars. Various literature sources were used for target selection, primarily the catalogues of HAeBe stars and HAeBe candidates by Thé et al. (1994) and Vieira et al. (2003).
The catalogue of Thé et al. (1994) contains six categories of stars; the stars selected for our study were obtained only from the first category, which contains stars historically known as HAeBe stars, or strong candidates of the group. According to the authors, all of these stars possess near- or far-IR excess and emission lines, associated with the presence of CS dust, discs and energetic outflows which are usually found in HAeBe stellar environments. On the other hand, Vieira et al. (2003) produced a catalogue of HAeBe stars and probable candidates from an initial search for new T Tauri stars (PMS stars of lower mass) using the Infrared Astronomical Satellite (IRAS) point source catalogue.1 Because the initial search was based on CS dust properties, it included HAeBe stars along with T Tauri stars. Vieira et al. extracted the HAeBe stars by filtering the data using specific requirements such as a spectral type earlier than F5, emission at Hα and a minimum level of IR emission. The majority of the stars were associated by the authors with a star-forming region. Based on the quality of these two literature sources and the arguments presented by their authors, we conclude that all of the stars in our sample are bona fide HAeBe stars. In total, 70 HAeBe stars have been selected with visual magnitudes lower than 12, spanning in spectral type from F5 to B0.
Measurements with high-resolution spectropolarimeters (such as ESPaDOnS@CFHT or Narval@TBL) have a high enough resolving power to take advantage of the information contained in the line profiles of metallic lines, as has already been demonstrated in earlier studies with the MuSiCoS spectropolarimeter (e.g. Wade et al. 2000; Petit et al. 2004). ESPaDOnS magnetic field measurements have standard errors which decrease strongly with decreasing v sin i and with increasing richness and strength of the metallic line spectrum (cf. Landstreet 1982; Shorlin et al. 2002). To fully exploit this dependence, and thus to obtain the most precise measurements possible, we have preferentially selected our targets for low v sin i (≲100 km s−1) where available v sin i data allowed us to perform such a selection. However, because accurate measurements of v sin i are not available for many HAeBe stars, a significant fraction of our targets (about one-third) turn out to be relatively rapid rotators.
OBSERVATIONS AND DATA REDUCTION
The 132 program star observations reported here were obtained between 2004 and 2010 using two high-resolution spectropolarimeters: the ESPaDOnS spectropolarimeter at the CFHT (80 spectra), and the Narval spectropolarimeter at the Télescope Bernard Lyot (52 spectra). The ESPaDOnS observations were obtained during six observing runs in 2004 (technical and commissioning runs), 2005 and 2006 (competitively allocated PI time), including the first scientific ESPaDOnS run. The Narval observations were obtained during seven observing runs between 2007 and 2010 (competitively allocated PI time).
The basic technical characteristics of ESPaDOnS and Narval are nearly identical. The polarization analysis unit is located at the Cassegrain focus of the telescope. The stellar image is formed on an aperture followed by a collimating lens. The beam then passes through a rotatable λ/2 retarder, a fixed λ/4 retarder, a second rotatable λ/2 retarder and finally a small-angle Wollaston prism, followed by a lens which refocuses the (now double) star image on the inputs of two optical fibres. This relatively complex polarization analyser is necessary because one of the fundamental design parameters for ESPaDOnS/Narval was very wide wavelength coverage (approximately 3700 Å to 1.04 μm). To have retarders which are approximately achromatic over this wide range, ESPaDOnS uses Fresnel rhombs. A single Fresnel rhomb acts as a λ/4 retarder, but deviates the beam, while two Fresnel rhombs in series form a λ/2 plate without beam deviation. To minimize mechanical complications, only the double (non-deviating) Fresnel rhombs are allowed to rotate; the configuration chosen is the minimum which allows one to analyse all of the Stokes polarization components (Q, U, V) by appropriate orientation of the axes of the successive retarders.
The two output beams from the Wollaston prism, which have been split into the two components of circular polarization (for this study) by appropriate retarder orientations, are then carried by the pair of optical fibres to a stationary and temperature-controlled cross-dispersed spectrograph where two interleaved spectra are formed, covering virtually the entire desired wavelength range with a resolving power of R ≃ 65 000. The I component of the stellar Stokes vector is formed by adding the two corresponding spectra, while the desired polarization component (Q, U, V) is obtained essentially from the difference of the two spectra. To minimize systematic errors due to small misalignments, differences in transmission, effects of seeing, etc., one complete observation of a star consists of four successive subexposures; for the second and third, the retarder orientations are changed so as to exchange the beam paths of the two analysed spectra (see Donati et al. 1997).
The actual reduction of observations is carried out at the observatory using the dedicated software package libre-esprit. libre-esprit subtracts bias, locates the various spectral orders on the CCD image, measures the shape of each order and models the (varying) slit geometry, identifies comparison lines for each order and computes a global wavelength model of all orders, performs an optimal extraction of each order, and combines the resulting spectra to obtain 1D intensity (Stokes I) and circular polarization (Stokes V) spectra. The Stokes V spectrum normally has the continuum polarization removed, as this arises mainly from instrumental effects and carries little information about the star. Each spectrum is corrected to the heliocentric frame of reference, and may optionally be divided by a flat-field and be approximately normalized (see Donati et al. 1997, and ESPaDOnS webpages2). Due to the presence of strong emission lines in the spectra of many of our targets, the automatic libre-esprit normalization fails to achieve a satisfactory rectification of the continuum. We have therefore turned off this option in libre-esprit, and normalized the final reduced 1D spectra manually, order by order.
Diagnostic null spectra called N spectra, computed by combining the four successive subexposures of polarization in such a way as to have the real polarization cancelled out (Donati et al. 1997), are also calculated by libre-esprit. The N spectra test the system for spurious polarization signals. In all of our observations, the N spectra are quite featureless, as expected. The final spectra consist of ASCII files tabulating I/Ic, V/Ic, N/Ic, and estimated uncertainty per pixel as a function of wavelength, order by order.
The log of spectropolarimetric observations is reported in Table 1. The 132 observations include 112 observations of 64 apparently non-magnetic program stars, nine observations of five magnetic program stars (the discovery and/or confirmation observations of each) and 11 observations of one possibly newly detected magnetic program star (HD 35929).

Because the program stars observed in this study are characterized by a large range of visual magnitudes (reflecting their diverse luminosities, distances and extinctions due to their surrounding environments), the distribution of their apparent magnitudes mV (shown in Fig. 1, left-hand panel) is rather broad (with a mean of 8.9, a minimum of 4.2 and a maximum of 11.9). As a consequence, our data yield a broad distribution of signal-to-noise ratios (S/N values, illustrated in Fig. 1, right-hand panel), ranging from below 100 per CCD pixel to over 1000.
FUNDAMENTAL PARAMETERS
Effective temperature and surface gravity determination
The temperature and gravity, as well as their errors, of each star was first taken from the literature, and has then been compared to our data as follows. For effective temperatures below 15 000 K, we have calculated synthetic spectra in the local thermodynamic equilibrium (LTE) approximation, using the code synth of Piskunov (1992). synth requires, as input, atmosphere models, obtained using the atlas 9 program (Kurucz 1993), and a list of spectral line data obtained from the Vienna Atomic Line Database3 (VALD; Piskunov et al. 1995; Kupka et al. 1999; Ryabchikova et al. 1999). Above 15 000 K we used TLUSTY non-LTE atmosphere models and the synspec code (Hubeny 1988; Hubeny & Lanz 1992, 1995), to calculate synthetic spectra. At all temperatures the synthetic spectra have been computed with a solar metallicity (see Section 4.2). Then we compared, by eye, the observed to the synthetic spectra, and if necessary adjusted the temperature (holding log g = 4.0 constant) until a best fit was achieved. For some stars, the temperatures found in the literature were not able to reproduce our spectra, and therefore we give here new determinations of Teff.
In this procedure we fixed the surface gravity log g = 4.0 because for most of the stars of our sample, the determination of log g using our data is not possible for the following reasons. First, the continuum level is very difficult to determine in echelle spectra and most of the Balmer lines are spread over two orders, making the determination of log g from the wings of the Balmer lines very imprecise. Then, the spectra of many of our targets are heavily contaminated with CS emission/absorption and especially in the spectral lines of Fe, Ti, Si and Cr, which makes impossible the determination of surface gravity from the ionization equilibrium of abundant species. Typical values of log g in HAeBe stars comprise between 3.5 and 4.5 (e.g. Folsom et al. 2012). We have therefore adopted a value of 4.0 for all stars for which a determination from our observations was not possible.
For a few Herbig stars whose metallic spectral lines are only very faintly contaminated with CS emission/absorption, we obtained very high quality, high-resolution spectra. To determine accurate effective temperature and gravity in these few cases, we developed an automatic procedure, based on a comparison of the observed spectrum to a grid of model spectra. The grid is composed of LTE synth3 models (Kochukhov 2007), computed using Kurucz's atlas 9 atmospheres. The models assume solar abundances and no macroturbulence, while the grid varies the microturbulence between 0, 1, 2, 3, 4 and 5 km s−1. The atomic line lists were extracted from VALD, for all lines with a predicted line depth greater than 0.01 times the continuum. The models in our grid range from an effective temperature of 6500 to 15 000 K, in steps of 100 K. In addition, the models range from 3.0 to 5.0 dex in log (g) in 0.5 dex steps. The rotational broadening and disc integration of the synth3 models used for comparison with the observed spectra was carried out using the code s3div (Kochukhov 2007).
For this procedure the spectral region between 420 and 520 nm was modelled, as lines in this region show the strongest sensitivity to temperature variations for stars with temperatures within our grid range. We used a brute-force search for the lowest χ2 by comparing the observation to each model within a pre-selected parameter space [corresponding to a pre-defined temperature range, a pre-defined range in log (g) and each value of microturbulence] of the grid. The initial search parameters were chosen based on photometric or spectroscopic literature estimates. For each model, we fit the v sin i to the observations using a χ2 minimization routine as well. The Balmer line regions were ignored due to imprecise continuum normalization of the short echelle orders and strong local emission.
Once the best-fitting model was identified, we carried out a visual comparison between the model and the observation to determine which regions (if any) were poorly fitted, likely due to contamination from CS material. We then reran our spectrum fitting procedure with these regions ignored to improve our fits. If an observation showed strong emission in metallic lines, this procedure would not provide a realistic estimate on the stellar parameters. Examples demonstrating the quality of fit we are able to achieve, for both a low v sin i and a high v sin i star, are shown in Fig. 2. The parameters derived in this way were used to check those obtained for the same stars from visual comparison and to refine the visual matching process.
We note that the effective temperatures derived from the visual comparison method depend on the assumed (solar) abundance and fixed log g = 4.0. To check the sensitivity of our atmospheric parameter determinations to these assumptions, we compare our Teff values with the results of Folsom et al. (2012), who derive Teff and log g from detailed spectrum synthesis of a sample of approximately 20 HAeBe stars, simultaneously determining the abundance table and microturbulence parameter. As is illustrated in Fig. 3, the results of our more approximate procedures are in reasonable agreement with those from detailed fitting. Ultimately, the results of the LSD procedure, which are used in particular to determine v sin i, to identify CS and interstellar line features and to diagnose the magnetic field, are only weakly sensitive to the details of the line mask, and errors in the adopted parameters of up to about ±10 to 20 per cent have little impact on the results.
The adopted effective temperatures and surface gravities are summarized in Table 2. The stars whose effective temperature and surface gravity have been determined using a visual inspection or the automatic procedure are labelled with a dagger (†) or a double dagger (‡), respectively. In these two cases no uncertainties have been determined in log g, and the indicated values are estimated at the model grid precision, i.e. ±0.5 dex.

Metallicities
In this work we have assumed a solar metallicity for all our objects (except one, HD 34282, that shows a very low metallicity; Merín et al. 2004) for the following reasons. The spectra of most of the stars of our sample are heavily contaminated with CS emission and/or absorption, making difficult a reliable abundance analysis, and therefore a metallicity determination. However, Folsom et al. (2012), using our data, have isolated the 20 stars of our sample showing only faint CS contamination, and have determined their abundances. They find that about half of them display λ Boo peculiarities, one of them is a magnetic Bp star (V380 Ori A), and all others are chemically normal with solar abundances. We know that magnetic Bp stars have peculiar abundances due to gravitational settling in their atmosphere (Michaud, Charland & Megessier 1981). These peculiarities do not reflect the global chemical composition of the star. The λ Boo peculiarities are not yet fully understood, but are also very likely due to a surface effect (e.g. Folsom et al. 2012). Among these 20 stars, there is therefore no evidence at all that their compositions deviate significantly from that of the Sun. While the Folsom et al. sample concerns only about 30 per cent of our sample, by extrapolation it is reasonable to assume that a large fraction of our targets have a metallicity similar to solar. Acke & Waelkens (2004) have analysed the spectra of 24 HAeBe and Vega-type stars and have found solar metallicities in 21 of them and λ Boo patterns in one of them. Following these works, it is therefore reasonable to assume a solar metallicity in all the stars of our sample (except HD 34282).
Luminosity determination
The photometric data employed to determine luminosities were taken from the Hipparcos and Tycho catalogues (Perryman & ESA 1997), when available, and from Herbst & Shevchenko (1999) and Vieira et al. (2003) otherwise. When a strong photometric variability (ΔV > 0.6 mag) has been observed by Hipparcos, we assumed that the reduced brightness of the star was due to variable occultation by CS matter situated around the star. In these few cases, we adopted the brightest Hipparcos magnitude HP value as the intrinsic (unocculted) magnitude of the star and we converted it to the Johnson system using the (v − I) colour of Hipparcos, and the conversion table of the Hipparcos and Tycho catalogues (Perryman & ESA 1997, p. 59). We used the visual magnitude (V) corrected for reddening (Av) obtained from the colour excess E(B − V) and a total-to-selective extinction Rv [Av = Rv × E(B − V)] of 5.0 (Hernández et al. 2004), the bolometric corrections and the distances of the stars, to estimate their luminosity. The intrinsic (B − V) and bolometric corrections of all stars have been obtained from the effective temperature reported in Table 2 and the calibration of Kenyon & Hartmann (1995). The errors on the luminosities have been determined by propagating the error on the distances. For the double-lined spectroscopic binaries (SB2) we have attempted a visual estimation of their luminosity ratio using the observed ratio of the individual spectral line depths of our data. However, in all but one of the systems we also had to adjust the temperatures of both components at the same time. The results being highly inaccurate we have not attempted an estimation of their error bars and therefore no errors on the luminosity of the individual components are reported for these systems. In the case of AK Sco, well-constrained temperatures of both components had been obtained by Alencar et al. (2003). It was therefore possible to derive an error bar on the luminosity ratio of the system, and therefore on the individual luminosities (see Appendix A and Table 2).
All the quantities are summarized in Table 2, while the sources of the data are detailed, star by star, in Appendix A. For three stars (HD 50083, HD 52721, HD 174571) no reliable distance could be found in the literature. We have therefore estimated their luminosity from their effective temperature and surface gravity by comparing their position in a log g–Teff diagram with theoretical evolutionary tracks (described in Section 4.4).
Mass and radius determination
We placed all the stars in an HR diagram (Fig. 4), with the error bars when available, and compared their positions with evolutionary tracks calculated with the cesam stellar evolutionary code (Morel 1997) version 2K. Using a 2D linear interpolation and a grid of 120 evolutionary tracks with masses from 1 to 20 M⊙, and mass steps varying between 0.01 and 1 M⊙ (depending on the mass and the position of the stars in the HR diagram), we determined the mass, radius and age of each star.
The errors have been determined using the intersection of the evolutionary tracks with the error ellipses, as defined by the errors in effective temperature, luminosity or surface gravity. When the ellipses are intersecting the ZAMS or the birthline, only the portion of the ellipse between the birthline and the ZAMS was considered.
The ages have been measured from the birthline, i.e the locus in the HR diagram where the newly formed stars become observable at optical wavelength, meaning that the CS matter in which the stars were buried during the protostellar phase becomes optically thin. We used the birthline of BM01 that has been computed with a mass accretion rate increasing with the luminosity of the growing star. We favoured a birthline calculated with a modulated accretion rate (instead of a constant accretion rate as computed by Palla & Stahler 1993) as it better fits the upper envelope of the distribution of massive Herbig Be stars in the HR diagram (see Fig. 4). Furthermore, Palla & Stahler (1993, hereafter PS93) argue that a constant accretion rate of 10−5 M⊙ yr−1 during the protostellar phase is a good approximation as it fits well the upper envelope of the known Herbig Ae/Be stars. However, their work was only including HAeBe stars of masses lower than 6 M⊙. Since their work, more massive stars have been identified as Herbig Be (e.g. Vieira et al. 2003; Martayan et al. 2008), while intermediate-mass T Tauri stars that are cooler and younger than Herbig Ae/Be star and that are identified as the progenitors of the Herbig Ae/Be phases, have also been found (e.g. Wolff et al. 2004; Hussain et al. 2009). The latter are filling the right-hand part of the HR diagram (with log Teff ≤ 3.8) and are evolving along the Hayashi track up to the radiative phase of the PMS evolution. We are therefore convinced that the BM01 birthline is a reasonable assumption for the start of the PMS phase at all masses.
In Fig. 4 all the stars of our sample are plotted, with circles for non-magnetic stars, squares for magnetic stars and a triangle for the candidate magnetic star. The BM01 birthline and the cesam ZAMS are also overplotted. We observe that two points (the open circles) are situated way outside of the theoretical limits of the PMS region (from the birthline to the ZAMS), even taking into account their error bars. For the two corresponding stars (HD 98922 and IL Cep) we are therefore not able to estimate their mass, radius and age using the cesam theoretical tracks. For stars situated just below the ZAMS, we have estimated the ranges of the parameters covered by the intersection area between the error ellipse and the HR diagram, and took the middle values. For the four magnetic stars, HD 190073, HD 200775, HD 72106 and V380 Ori, we have adopted the masses and radii reported in the papers that describe their spectroscopic and magnetic analyses (Catala et al. 2007; Alecian et al. 2008a; Folsom et al. 2008; Alecian et al. 2009b). However, we have redetermined their ages as different birthlines were used in these papers.
This method takes into account neither the uncertainties in the metallicity (however, see Section 4.2), nor the choice of the birthline. The inferred masses, radii and ages are therefore approximate, but will be useful when considering comparisons between the stars themselves. The masses, radii and ages are summarized in Table 2. In the same table we also give the PMS duration for each star, and the predicted radius that each star will have once it reaches the ZAMS. Both have been calculated by assuming a mass-constant evolution for each star. The PMS duration has been computed from the birthline. In the case of HD 34282, we did not calculate the ZAMS radius and the PMS duration because our models are of solar metallicity. HD 98922 and IL Cep fall well outside of the HR diagram, even when the errors on their temperatures and luminosities are taken into account. Furthermore, no distance, accurate enough to estimate a luminosity with reasonable error bars, could be found for HD 250550. Therefore no age, mass, radius, ZAMS radius and PMS duration could be estimated for these stars.
THE LEAST-SQUARES DECONVOLUTION PROFILE ANALYSIS
The LSD method
In order to increase the S/N of our line profiles, we applied the LSD procedure to all spectra (Donati et al. 1997). This procedure combines the information contained in many metal lines of the spectrum, in order to extract the mean intensity (Stokes I) and polarized (Stokes V) line profiles. In Stokes I, each line is weighted according to its central depth, while in Stokes V the profiles are weighted according to the product of the central depth, wavelength and Landé factor. These parameters are contained in a ‘line mask’ derived from a synthetic spectrum corresponding to the effective temperature and gravity of the star given in Table 2. The construction of the line mask for each star involved several steps. First, we used Kurucz atlas 9 models (Kurucz 1993) to obtain generic masks of solar abundances, and of Teff/log g following the Kurucz models grid. Our masks contain only lines with intrinsic depths larger or equal to 0.1, which, according to the S/N of our data, is sufficient. We then excluded from the masks hydrogen Balmer lines, strong resonance lines and lines whose Landé factor is unknown. At this stage, the mask contains all predicted lines satisfying the initial assumption of the LSD procedure, i.e. a similar shape for all spectral lines considered in the procedure. In the following this mask will be called the ‘full mask’. Finally, each mask was carefully examined in order to exclude lines predicted by the models, but not appearing in the spectrum, as well as lines contaminated by non-photospheric features. This final ‘cleaning’ procedure is explained in Section 5.2 and detailed for each star in Appendix A. Following this procedure, we executed LSD using the full and cleaned masks and the observed spectra, obtaining for each star the mean intensity Stokes I profile, the mean circularly polarized Stokes V profile and the null N profile. Fig. 5 shows the LSD I, V and N profiles for two stars: one with a magnetic field detection and one without. In both cases, as well as in all of our observations, the N profiles are null indicating the absence of spurious polarization signals, and confirming that the Zeeman signatures detected in the magnetic stars are real. The use of two separate masks per star is justified in the following sections. The analysis of the LSD I profile and the rotation velocity measurements are described in Section 5.2, while the magnetic analysis performed using the I and V profiles is detailed in Section 6.
The LSD method implies that all lines of the spectra have a similar shape, differing only in their relative strength. The strengths depend on the central depth when the method is applied to an I spectrum, and on the central depth and Landé factor for a polarized V spectrum. This hypothesis is reasonable for purely photospheric lines. However, in the case of a spectrum contaminated with CS features, these hypotheses should be discussed. The CS features contaminating the photospheric lines of the spectra of the Herbig Ae/Be stars have the same shape (except in few lines like the Balmer, Ca ii H&K or Na D lines, which are removed from the mask). However, their relative strength is not dependent on the central depths of the photospheric lines, which are used to weight each line in the LSD procedure. Therefore, the LSD method, by averaging the contaminated lines, applies inappropriate weights to the CS contribution, while taking correctly into account the different weights of the photospheric lines. In the LSD procedure, using wrong weights does not change the global shape of the resulting profile; however, its relative strength (with respect to the V profile, for example) cannot be trusted. Therefore, the strength of the CS contribution of our LSD I profiles must be investigated in more detail before it can be reliably used to drawn any quantitative conclusions. However, its shape can be modelled and removed to be able to analyse the photospheric contribution of the I profile, which is one of the interests for this paper. We describe in the following section how the CS contamination has been handled in this study.
Fitting of the LSD I profiles
The LSD I profiles computed with the full mask reveal a rather complex average of the lines of the spectrum included in the line mask. Most HAeBe stars show CS emission and absorption in their spectrum; these effects are also reflected in the LSD profiles. Those lines that are most strongly contaminated by CS emission can be easily identified directly in the spectrum itself, and excluded from the mask. For some of the stars, the resulting LSD profiles show a relatively clean rotational profile indicative of simple photospheric absorption. For others, the resulting profiles still show significant CS absorption and/or emission that is not possible to remove by further refinement of the line mask. However, the investigations of rotation and magnetic fields in Papers II and III require that we are able to extract an approximation of the uncontaminated photospheric profiles in order to infer v sin i and to model the magnetic constraint imposed by Stokes V.
To characterize the various contributions to the LSD I profiles, we have performed a least-squares fit to each of the LSD I profiles using several models. In the first case we consider a simple photospheric profile modelled using the convolution of a rotation function (depending on the projected rotational velocity v sin i and the radial velocity of the star vrad), and a Gaussian (approximating the local photospheric profile) whose width is fixed and computed from the spectral resolution and the macroturbulent velocity (Gray 1992). This convolution will be called the photospheric function. The free parameters of the fitting procedure are the line depth, v sin i and vrad. In order to fit the wings of the observed LSD profiles of our sample, a macroturbulent velocity (vmac) is frequently required to be added to the model. Only a few stars of our sample have LSD I profiles suitable for estimating the value of vmac, and the typical value is found to be around 2 km s−1. The other stars of our sample (i.e. most of them) display too large a Doppler broadening, and/or the wings of the profile are sufficiently contaminated by CS features, that they do not allow us to obtain useful information about vmac. Nonetheless, we assumed that a macroturbulent velocity field is present near the surface of the star, and we adopted for all the stars an isotropic macroturbulent velocity of 2 km s−1. However, taking into account a vmac ∼ 2 km s−1 seems to improve the fit, when fitting with the eye, only for stars with v sin i lower than 40 km s−1. In order to estimate the error on the v sin i introduced by fixing vmac, we varied the value of vmac between 0 and 4 km s−1, and we find that it introduces significant variations of v sin i only if v sin i is lower than 10 km s−1. For v sin i between 10 and 40 km s−1, changing vmac modifies the value of v sin i within the error bars. For v sin i larger than 40 km s−1, changing vmac has no impact on v sin i. The macroturbulent velocity is therefore not a significant parameter to be considered within this fitting procedure. It has been included in all the fitted models for consistency from one star to the other, but should only be considered with caution at very low v sin i (lower than 10 km s−1).
The second model considers one or more Gaussian functions meant to model the CS features present in the LSD I profile. These functions are added to the photospheric function with the aim of providing the best reproduction of the observed profile. The parameters of each Gaussian contributing to the CS function are the full width at half-maximum (FWHM), the centroid position and the amplitude. The amplitude may be either positive or negative, corresponding to emission or absorption contributions. Depending on the star analysed, we require between zero and four CS functions to fit the Stokes I profile. Hence, the number of fitting parameters required to reproduce the LSD I profiles ranges from 3 to 15. For a few stars for which this simple model was unable to reproduce features in the observed profile, an alternative method we applied was to suppress from the fit the regions contaminated with CS (or other) features. We accomplished this by assigning a null weight to all points inside the affected region, and fit the profile with only a photospheric function.
The LSD profiles of our observations show systematically a continuum level lower than 1 (while the spectra are all normalized to 1). We believe that this is due to spectral features not taken into account in the LSD procedure, and not due to poor continuum normalization or to a reduction problem, for two reasons. First, multiple LSD profiles of a star obtained at different times show a continuum at the same level. However, multiple observations of different stars do not have the same continuum level, suggesting that the choice of the mask might determine the level of the continuum. Secondly, when we apply the LSD procedure on a simulated ESPaDOnS or Narval observation, in which the continuum is by construction perfectly normalized to 1, the continuum level of the resulting I profile is also lower than 1.
In order to simplify the fitting procedure and avoid additional parameters to fit, we have normalized each profile before fitting them. The continuum levels have been determined by fitting a line between two points chosen by eye on each side of the profiles. The profiles are then divided by the fitted continuum. We have checked that this normalization process does not introduce significant errors by repeating the procedure many times and checking that the fitted parameters converge all towards the same value.
A remarkable result of this procedure is the conclusion that the mean line profiles of most HAeBe stars can be satisfactorily reproduced by a simple model consisting of the sum of a rotationally broadened photospheric profile and a small number of local absorption/emission profiles assumed to be contributed by the CS environment. The analysis of the quantitative characteristics of the CS-contributed profiles will be described in a future paper.
As an additional complication, some stars in our sample are double-lined spectroscopic binaries (see Section 5.3). In these cases, we fitted the LSD I profiles using the sum of two photospheric functions, each one having independent fitting parameters. Examples of the results of the fitting procedure are shown in Fig. 6.
This fitting procedure is automatic and requires as input first guesses for each free parameter. We checked the uniqueness of the derived fit by modifying the first guesses, and checking that whatever the first guesses, the fits always converge towards a unique solution. This verification procedure was always successful for the photospheric parameters (the photospheric line depth, v sin i and vrad). However, in some cases when one or more Gaussian CS functions was required, we could find multiple solutions (e.g. the addition of a Gaussian in emission or a Gaussian in absorption could give fits of comparable quality). In those cases we checked individual spectral lines in order to determine which of the solutions was the most consistent with the observed spectrum. Whenever multiple observations were obtained for the same star, we also chose the solution the most consistent over all observations.
When multiple observations were obtained for the same star with similar S/N values, we performed a simultaneous fit to the whole set of observations, by forcing the photospheric parameters (depth, v sin i, vrad) to be the same for each of the observations. When necessary, one or more Gaussian functions were added to the profiles, with independent parameters for each observation.
We checked that changing the effective temperature and gravity of the masks, within the error bars, do not change our determination of our v sin i values. The fit performed to reproduce the shape of the LSD I profile is dominating the uncertainties. The uncertainties on the adopted parameters (see Table 2) have therefore been determined by calculating the confidence intervals at a level of 99.73 per cent, as described in Press et al. (1992, p. 697).
After completing the analysis of the LSD profiles, we checked that the derived v sin i were consistent with individual spectral lines in the reduced spectra. The adopted values of v sin i and vrad are summarized in Table 2, and the fitting procedure for each of the spectra is described in Appendix A. In the case of MWC 1080, no photospheric lines could be identified in the spectrum, therefore no v sin i values could be measured.
The discovery of spectroscopic binaries
The inspection of the LSD profiles allowed us to easily identify a number of spectroscopic binaries among the stars in our sample. Among the stars not detected as magnetic, a total of five SB2 systems were identified: three previously known or suspected (AK Sco, HD 287823, IL Cep), and two new discoveries previously unreported in the literature (HD 203024 and HD 290409). Based on the detection of a LiI lines at 6707 A, Corporon & Lagrange (1999) claimed the presence of a low-mass companion orbiting HD 203024. However, this claimed companion cannot be the spectroscopic companion that we detect because its temperature is too high. We therefore cast some doubts on the stellar nature of the feature observed at ∼6708 Å, and leave open the interpretation of its origin.
For each of the SB2 systems, we have attempted a determination of the effective temperature of both components, as well as of their luminosity ratio. The description of each system is detailed in Appendix A.
MAGNETIC FIELD DIAGNOSIS
Method
Each of the spectra that we have acquired with ESPaDOnS and Narval was obtained in Stokes V polarimetric mode, in order to allow us to measure the longitudinal Zeeman effect in spectral lines. We employ two methods to detect magnetic fields in our program and standard stars. First, we use the Stokes V spectra to measure the mean longitudinal magnetic field strength 〈Bz〉 of each star at the time of observation. This is the conventional measure of field strength normally used for detection of magnetic fields in MS stars (e.g. Landstreet 1982). However, because of the high value of the resolving power, we can also examine spectral lines for the presence of circular polarization signatures: Zeeman splitting combined with Doppler broadening of lines by rotation leads to non-zero values of V within spectral lines even when the value of 〈Bz〉 is close to, or even equal to, zero. This possibility substantially increases the sensitivity of our measurements as a discriminant of whether a star is in fact a magnetic star or not, as discussed by Shorlin et al. (2002), Silvester et al. (2009) and Shultz et al. (2012).
If a significant signal (i.e. with a MD or DD) is detected within the line, while always remaining insignificant in the neighbouring continuum and in the N profile, and is detected in multiple observations, we conclude that the star is unambiguously magnetic.
The magnetic HAeBe stars detected within the survey
Of the 70 stars observed with ESPaDOnS and Narval, six show Stokes V Zeeman signatures in their LSD profiles. Four of these stars (V380 Ori, HD 72106, HD 190073 and HD 200775) were unambiguously detected for the first time as a result of this study. First results for V380 Ori and HD 72106 were reported by Wade et al. (2005); for HD 190073 by Catala et al. (2007); and for HD 200775 by Alecian et al. (2008a). In addition, one HAeBe star for which magnetic field detections were previously reported (HD 36982 = Par 1772 = LP Ori ; Petit et al. 2008) is confirmed to be magnetic. Finally, one new suspected magnetic HAeBe star (HD 35929) is reported here. However, as HD 35929 is a δ-Scuti pulsating star (Marconi et al. 2000), more analysis and observations are required to verify that the signature detected in the V profile is of magnetic origin.
In Table 3, for each of the detected program stars, we list the observational details corresponding to the ESPaDOnS/Narval observations from which the presence of a magnetic field was first inferred. In addition, in Fig. 4 we show the positions on the HR diagram of the magnetic HAeBe stars of our sample.

Each of the five detected stars has been or will be discussed in detail in a dedicated paper (e.g. HD 190073 by Catala et al. 2007, HD 200775 by Alecian et al. 2008a, HD 72106 by Folsom et al. 2008 and V380 Ori by Alecian et al. 2009b). They will not be discussed further here.
Five other magnetic HAeBe stars have been discovered and confirmed during recent years, as part of parallel observational programs with ESPaDOnS, Narval and FORS1 on the Very Large Telescope (ESO, Chile), or the Semel Polarimeter (SEMPOL; Semel 1989; Semel, Donati & Rees 1993; Donati et al. 2003) coupled with the spectrograph UCLES on the Anglo Australian Telescope (AAT, Australia). The first magnetic detections and their confirmations are reported or are to be reported in other publications: HD 101412 (Wade et al. 2007; Hubrig et al. 2009; Paper IV), HD 104237 (Donati et al. 1997; Paper IV), NGC 6611 601 (Alecian et al. 2008b), NGC 2244 201 (Alecian et al. 2008b) and NGC 6611 83 (Alecian et al. 2009a). We are mentioning them in this paper for the sake of completeness; however, they will not be included in the statistical analyses that will be presented in Papers II and III as they are not part of the survey presented in this series of papers. They will not be discussed any further here.
Magnetic analysis of the remaining sample
The polarized spectra of the undetected stars, i.e. displaying no magnetic signatures, contain a valuable information that we want to extract: the upper limits on admissible surface magnetic fields. In this section we first describe the problems that a typical spectrum of Herbig Ae/Be stars can bring in evaluating realistic values of such limits due to the CS contribution to the spectra. Then we propose the method that we adopted to solve the problems: the hybrid method.
The CS contribution to the Stokes I and V spectra
Before discussing the analysis of the stars in which no firm magnetic detections was obtained, it is instructive to consider the formation of the stellar spectrum, beginning in the photosphere of a magnetized HAeBe star. Upon exiting the ‘top’ of the photosphere, the (absorption) lines will be partially circularly polarized due the magnetic field. As the flux propagates into the CS environment, it will undergo absorption or emission contributions due to the CS material. As observed in the spectra of real HAeBe stars, this can strongly modify the Stokes I line profiles. However, we expect that the magnetic field strength will decrease rapidly with distance from the star as 1/r3 for a dipole, and more rapidly for more complex fields. Therefore the contribution of the Zeeman effect to Stokes V in the CS environment should be very small compared to the photospheric contribution. In other words, the CS contribution to the flux is expected to be negligibly circularly polarized. A consequence of this conclusion is that the observed Stokes V/Ic spectrum of a magnetic HAeBe star is expected to be reflective of the photospheric spectrum of the star, even if the Stokes I spectrum is strongly modified by the CS environment. An important implication of this conclusion it that CS contamination of spectral lines cannot serve to ‘hide’ the Zeeman signatures produced by a photospheric magnetic field. Note, however, that because the V spectrum is normalized to the inferred continuum, this conclusion and its implication rely on the assumption that no significant veiling is present (Ghandour et al. 1994; Folsom et al. 2012). Although veiling does not modify the absolute amplitude or shape of the Zeeman signature, it serves to increase the noise, and could therefore render a Zeeman signature undetectable.
The LSD profiles produced for line profile analysis in Section 5.2 with the cleaned masks are heavily filtered: many lines have been removed from the line masks in order to reduce the CS contribution and to reveal the photospheric profile. In the case of the Stokes V profile, this results in a relatively high noise level (because of the relatively small number of lines used in the deconvolution) and consequently low sensitivity to magnetic fields (see the S/N in V obtained from both full and cleaned masks in Table 1). However, in contrast to the Stokes I profile, we have concluded that Stokes V is not strongly modified by the CS contribution to the line. Therefore the most sensitive magnetic diagnosis should be obtained by including as many lines as possible in the mask. However, as we have seen in Section 5, LSD Stokes I profiles derived from such masks can be heavily modified by CS contributions. Even if the Stokes V Zeeman signature is not modified significantly, using such contaminated I profiles has two important consequences for our diagnosis of the magnetic field. First, uncertainty is introduced into the appropriate integration range to use to compute the longitudinal magnetic field in equation (1), and the reduced χ2 in equation (2). Secondly, the equivalent width of the Stokes I profile (i.e. the denominator of equation 1) is modified. Both of these consequences can change the inferred values of the longitudinal field and its error bar, while the first can influence the derived FAP. Of these, the impact on the longitudinal field is the most severe. For example, CS emission/absorption superimposed with the photospheric spectral lines can reduce/increase the equivalent with of the Stokes I profile significantly, artificially increasing/decreasing the derived longitudinal field and its error. In the absence of a magnetic detection, the longitudinal field error bar is the only important statistical quantity, as it provides an estimate of the upper limit on admissible fields. Because it is sensitive to CS contamination of Stokes I, it is important to understand, and potentially limit, the CS contribution to the I profile (even if the V profile is unmodified).
A hybrid approach
With these insights, we approached the problem of obtaining realistic quantitative longitudinal field measurements of the 65 program stars for which no significant magnetic field was detected. Our goal was to obtain measurements of the longitudinal field for which the error bars were simultaneously accurate and precise. The first option considered was to use the cleaned line masks described in Section 5. These have the advantage that they reveal, in many cases, the photospheric profile of the star. The disadvantage is that, in many cases, this is accomplished by excluding most of the lines – especially strong lines – that contribute significantly to reducing the Stokes V noise level. The second option was to use the full line masks. This has the advantage of reducing the noise level of Stokes V to the greatest extent, but the disadvantages of a strongly contaminated I profile (as described above). We considered using masks for which an intermediate level of cleaning had been applied, but it was not obvious to what extent to clean the masks, nor was it clear that we were not simply combining the uncertainties and disadvantages of both options 1 and 2.
In reality, we wished to combined the advantages of options 1 and 2, essentially by combining the more nearly photospheric Stokes I profiles obtained from the cleaned masks and the high-S/N Stokes V profiles from the full masks. While such an approach can solve the problem of determination of the integration range, it does not solve the problem of determination of the longitudinal field: the I and V profiles obtained from two different masks correspond to averages of different lines with different weights, and are therefore not directly comparable or quantitatively compatible in equation (1).
As a solution to this problem, we decided to take advantage of the atmospheric and spectral parameters determined in Sections 4 and 5 and to compute the approximate photospheric spectrum of each star using spectrum synthesis. We used the synth3 LTE spectrum synthesis code (Kochukhov 2007) and effective temperature, surface gravity, v sin i and vrad of each star (reported in Table 2) to compute its photospheric Stokes I spectrum with the same spectral domain and resolution as ESPaDOnS/Narval. We assumed solar abundances. To each synthetic spectrum we added synthetic Gaussian noise (calculated from the S/N of the spectra) that varied with wavelength in the same manner as in the observed spectrum. For each observed spectrum we then used the full line mask appropriate to the star to extract the Stokes I LSD profile from the synthetic spectrum, and the Stokes V LSD profiles from the observed spectrum. Combining the I and V profiles, this ultimately resulted in ‘hybrid’ LSD profiles consisting of the real, observed Stokes V profiles and a synthetic Stokes I profile, both extracted using the same mask. The advantage of this approach is that we avoid the uncertainty related to CS contributions to the Stokes I profile. On the other hand, we introduce uncertainty related to the compatibility of the synthetic photospheric spectrum with the real stellar photospheric spectrum.
Tests and effectiveness of the hybrid method
Using an integration range equal to the 1.2 times the measured v sin i of each star symmetric about the measured radial velocity, we evaluated equations (1) and (2) for each of the hybrid LSD profiles. For comparison, we also performed the same measurements, but using the original LSD profiles extracted using the full masks obtained only from the observed spectra. These measurements are listed in Table 4.

Based on the analysis of Section 5, we conclude that some of our observations have relatively small CS contamination, and are dominated by the photospheric component. We identified 17 stars (corresponding to 35 observations) for which this was the case; these stars are underlined in Table 4. We have used these observations as a test of the accuracy of this method by comparing the longitudinal field extracted using the LSD profiles with observed Stokes I profile, and those with the synthetic Stokes I profile. For stars with purely photospheric spectra we expect the longitudinal field error bars to agree. (Because the value of the longitudinal field itself is determined by the details of the noise pattern, we do not expect those values to agree, except that they should have values compatible with the uncertainties.) The results of this comparison are shown in Fig. 7.
The upper panel of Fig. 7 shows the derived value of the longitudinal field error bar using the synthetic Stokes I profile (σsyn, on the horizontal axis) versus that derived from the real Stokes I profile (σobs, on the vertical axis) of the stars with mostly photospheric spectra. As can be seen, the correspondence between the error bars is quite close, with most points clustered tightly about the line x = y. The detailed agreement is summarized in the lower panel, which shows a histogram of the ratio σsyn/σobs. The median of the distribution is 0.85, the mean is 1.2 and the standard deviation is 0.4. Most of the values of σsyn/σobs are clustered within ±0.15 of unity, although two significant outliers (the stars HD 34282 and HD 68695) exist at ∼1.5. The dispersion results from (usually) small differences in the equivalent widths of the computed versus observed Stokes I profiles. A comparison of the observed and computed Stokes I profiles for four of the stars with mostly photospheric spectra is shown in Fig. 8. The stars are typical of the sample, and illustrate the level of agreement usually achieved. Clearly some of the differences in the Stokes I profiles result from small CS contributions to the real spectrum (e.g. HD 244604, lower-left panel). The remainder we attribute mainly to errors in the adopted atmospheric parameters and the detailed chemistry of the star. HD 34282 and HD 68695 are both instructive in this respect: a detailed examination of their spectra reveals underabundances of the Fe peak elements that dominate their spectra, while the abundance of oxygen appears to be solar. This suggests that these two stars represent further examples of HAeBe stars with λ Boo abundance patterns (Cowley et al. 2010; Folsom et al. 2012). In fact, one of these stars (HD 68695) was analysed by Folsom et al., who found it to exhibit clear λ Boo abundance peculiarities. From Fig. 7 we conclude that typically our spectrum synthesis approach is able to determine the expected longitudinal field error bar within ±20 per cent, although larger deviations sometimes occur for stars with strongly peculiar chemistry.
Examples of the remaining stars – those with profiles with significant CS contributions – are shown in Fig. 9. In these cases the magnetic diagnosis is highly uncertain, and often no reasonable diagnosis can be performed using the observed Stokes I profile. When we measure the longitudinal fields of the hybrid profiles of these objects, we find that while sometimes the error bars are reduced, sometimes they increase significantly. Examination of individual profiles reveals that often when the error bar derived by our method is significantly larger than that from the observed profile, it is because the observed profile is in strong emission or contains strong CS absorption, artificially increasing the magnitude of the equivalent width (e.g. BD+61 154, lower-right panel of Fig. 9, HD 144668 and BF Ori, upper panels of Fig. 9). On the other hand, partial infilling of the photospheric profile as a result of CS contributions may reduce the equivalent width, thereby increasing the error bar relative to that obtained from a synthetic profile (e.g. AB Aur, lower-left panel of Fig. 9). In some extreme cases, the infilling can produce an observed equivalent width very close to zero, resulting in a divergent longitudinal field and error bar (e.g. HD 50083, observed on 2008 April 3. Interestingly, the observation obtained on 2007 November 12 has much less infilling, and a much more realistic error bar).
The results we obtain from our hybrid analysis are very different from those that we would obtained using the clean masks derived for the profile analysis of Section 5.2. To illustrate, in Table 4 there are 44 measurements (corresponding to 19 stars) with ‘hybrid’ error bars smaller than 100 G. In contrast, analysis of the ‘clean’ profiles results in only 10 measurements smaller than 100 G. For some stars for which the raw and hybrid profiles yield quite good errors (a few tens of gauss), the clean profiles produce errors of hundreds of gauss. This confirms our view that in many cases, the line masks required to obtain a relatively pure photospheric profile for determining e.g. v sin i are not suitable to obtain profiles yielding the most realistic magnetic diagnosis.
Based on these experiments and examination of individual profiles, we conclude that our hybrid approach provides a useful way of determining the longitudinal magnetic field for a large and diverse sample of HAeBe stars, and that while inherent uncertainties exist in the determination of the longitudinal field using synthetic photospheric Stokes I profiles, those uncertainties (errors in atmospheric parameters, detailed chemistry) are better controlled and understood than the uncertainties associated with the determination of 〈Bz〉 using the observed Stokes I profiles. We therefore recommend the use of the hybrid determinations of 〈Bz〉 for characterization of the magnetic fields of individuals stars or samples of stars for which poorly understood contamination of Stokes I by CS environment is a problem.
In order to evaluate the impact of our choices of the masks on the 〈Bz〉 and their uncertainties, we have computed new LSD profiles of different stars of our sample with various masks of different temperature, gravity and abundance. We have then computed new values of 〈Bz〉 and compared them to those of Table 4. We selected stars in our sample of various spectral types and rotation velocities, and with small CS contribution. We changed the temperature within the error bars (Table 2), log g from 3.5 to 4.5, and the abundance at ±25 per cent. We find that 〈Bz〉 varies within the error bars in all cases. The uncertainties on 〈Bz〉 vary by a factor of <1 per cent when log g and the abundances are varied. When we change the temperatures, the uncertainties vary from 1 per cent (for large uncertainties of ∼800 G) to 10 per cent (for uncertainties lower than ∼100 G).
Of the 70 stars observed in our survey, 65 (93 per cent) show no direct evidence of a magnetic field. The derived characteristics of the longitudinal magnetic fields of the sample are summarized in Table 4. The magnetic geometries of the detected stars, as well as interpretation of the general magnetic properties of the sample from the distributions illustrated in Fig. 10, will be discussed in detail in Paper III.
CONCLUSIONS
This paper is the first of a series that presents the results of a high-resolution spectropolarimetric analysis of a sample of 70 Herbig Ae/Be stars. We carried out this analysis in order to address the problems of magnetism, angular momentum evolution and CS environment during the PMS phase of intermediate-mass stars.
We obtained 132 high-resolution Stokes I and V spectra of 70 HAeBe stars using the instruments ESPaDOnS at CFHT and Narval at TBL. In this paper, we have described the sample selection, the observations and their reduction, and the measurements that will comprise the basis of much of our following analysis. We have described the determination of fundamental parameters for each target.
The published effective temperatures have been verified by a visual comparison of observed with synthetic spectra. For some stars, new determinations of Teff are given here. In the case of a few stars with high-S/N observations weakly contaminated by CS material, we have redetermined their Teff with an automatic procedure described here.
The luminosities have been estimated using the most reliable distance and photometric data that we could find in the literature.
The radius, mass and age have been determined by comparing the position of the stars in an HR diagram with PMS evolutionary tracks computed with cesam. The ages have been measured from the birthline of BM01.
We discuss the LSD method that we have applied to each of our spectra, including the careful selection, editing and tuning of the LSD line masks. We describe the fitting of the LSD Stokes I profiles using a multicomponent model that yields the rotationally broadened photospheric profile (providing the projected rotational velocity and radial velocity for each observation) as well as CS emission and absorption components. The v sin i measurements are summarized in Table 2.
Finally, we detail the method that we used to confidently affirm that a star is magnetic. We diagnosed the longitudinal Zeeman effect via the measured circular polarization inside spectral lines. In this survey, five (out of 70) HAeBe stars have been confirmed to be magnetic (V380 Ori and HD 72106 reported by Wade et al. 2005; HD 190073 by Catala et al. 2007; HD 200775 by Alecian et al. 2008a; LP Ori by Petit et al. 2008). Four of them have been discovered within this program. One star (HD 35929) is reported here as a new suspected magnetic star. We also present the ‘hybrid’ method that we have adopted in order to obtain realistic quantitative measurements of the magnetic fields of the 65 non-magnetic stars. The results are reported in Tables 3 and 4.
As an appendix, we have also provided a detailed review of each star observed.
In three forthcoming papers we will present out analysis of the rotational properties of the sample (Paper II), the magnetic properties of the sample (Paper III) and the properties of the CS environment of the Herbig Ae/Be stars (Paper IV).

APPENDIX A: ANALYSIS OF INDIVIDUAL STARS
This appendix describes the approach that has been followed in order to determine the v sin i of all the stars of our sample, and the fundamental parameters (luminosity, effective temperature and surface gravity) required to estimate the masses and ages of the stars, which will be used in the statistical analysis described in Paper II. The basic procedure we have followed has been to first check that the effective temperature found in the literature corresponds to our data, and modify it if necessary. Then we have computed the LSD profiles for most of the data, using masks of appropriate temperature and gravity for each star, and fitted them (see Section 5). Sometimes it was necessary to add one or more Gaussian functions to the photospheric rotational velocity broadening function in order to obtain a better fit, and hence a more accurate value of the v sin i. This paper does not aim to propose a physical origin of these Gaussian functions. Most of them are assumed to have a CS origin. However, a more detailed analysis of the non-photospheric spectral features observed in the spectra (and in the LSD profiles) of our sample will be presented in a forthcoming paper. This appendix summarizes only the information required to fully understand the method that we applied to determine the v sin i of the stars.
For each of the stars we compared the observed normalized spectra with a grid of synthetic spectra, in order to check the published values and estimate new ones if required. As described above, these spectra assume solar chemical composition. In most cases the effective temperature could be estimated from this comparison, but not the surface gravity, due to imperfect continuum normalization of individual echelle orders and/or CS contamination. Therefore, unless specified, we used by default a surface gravity log g = 4.0 (CGS) (see Section 4.1). In order to better understand the shape of the LSD profiles and the choice of the adopted mask, a description of the non-photospheric features has been added for each star. In these descriptions, the Balmer profile emission types that are sometimes mentioned have been classified according to the system of Beals (1953).
For each one of the stars, a short discussion has also been added to support their PMS nature, and therefore to justify their membership to our sample. The references of the photometric data and the distances used to derive the luminosity are also detailed. In the cases of stars that are members of the Orion OB 1 association, the distance adopted is the weighted mean of the distances of the six subgroups described by Brown et al. (1994).
Finally, apart from LP Ori, for which we obtained more data since its magnetic detection reported in Petit et al. (2008), this appendix concerns only the stars that have not been detected as magnetic. For the magnetic stars we refer the reader to the following papers: Catala et al. (2007), Alecian et al. (2008a), Folsom et al. (2008), Alecian et al. (2009b) and Paper IV.
BD−06 1259 (= BF Ori)
BF Ori is a member of the subgroup c of the Ori OB 1 association (Warren & Hesser 1978), at a distance of 375 pc (Brown et al. 1994). It belongs to the UXOR subclass of HAeBe objects (hereafter UXOR stars; Mora et al. 2004), whose the prototype is UX Ori (see Section A61 in the online version of this paper). These stars are strong photometric variables. For the same reasons as for UX Ori, we used the Hipparcos photometric data (Perryman & ESA 1997) at maximum brightness (VT = 7.81 mag, BT = 7.85 mag, in the Tycho system), and converted them to the Johnson system (see the method in Section A61 in the online version of this paper). We find V = 7.85 mag and (B − V) = −0.028 mag, values that have been adopted to derive the luminosity of the star. BF Ori displays strong near-IR excess, very likely due to the presence of an optically thick CS accretion disc (Hillenbrand et al. 1992).
The spectrum of BF Ori is very complex, highly variable and similar to other UXOR stars. In the 2005 February spectrum, we can distinguish two classes of spectral lines among the metals. The first class consists of strong and broad CS absorption features at the positions of the predicted strong photospheric lines. These lines are still observed in the 2009 March spectrum, with different shapes and increased depth. The second class of lines concerns the predicted weak lines of the spectrum, which show a photospheric component on which is superimposed a narrower CS absorption. In our 2009 spectrum these lines show only photospheric components. As with other UXOR stars, these transient absorption features are assumed to come from gaseous clouds in the disc of the star (see Section A61 in the online version of this paper).
The Balmer lines from Hδ to Hβ show strong absorption components superimposed on the cores of the photospheric lines, with weak emission in the wings of the absorption component. The amplitudes of these features increase with wavelength, and their shape has changed between our two observations. Hα is in emission with a double-peaked profile of type VI and a strong central absorption that goes below the continuum. The amplitude of the emission doubled between 2005 and 2009. The Ca ii K line, the He i lines at 5875, 6678 and 7065 Å, and the O i 7775 Å and O i 8446 Å triplets display very strong (stronger than predicted) absorption profiles. The three IR Ca ii lines at 8498, 8542 and 8662 Å (hereafter the Ca ii IR triplet) show strong and broad emission profiles superimposed on the three photospheric absorption lines. The Paschen lines seem also to be slightly contaminated with CS emission.
The wings of the Balmer lines are consistent with the temperature and surface gravity determination of Mora et al. (2004, Teff = 8750 ± 250 K, log g = 4.0 ± 0.5). We have cleaned the Kurucz mask by rejecting as many contaminated lines as possible. The resulting LSD profile for 2009 shows only a photospheric component. However, the 2005 profile still shows a photospheric line with a superimposed CS absorption component. We first tried to fit both observations simultaneously using the following model: a photospheric profile + a Gaussian function in absorption for the 2005 profile, and only a photospheric profile for the 2009 observation. However, we found that fitting the 2009 profile only resulted in a more accurate value of v sin i. We therefore adopted this value. The resulting fit is shown in Fig. A1.
