Rotational variation of daughter species production rates in Comet 103P/Hartley: Implications for the progeny of daughter species and the degree of chemical heterogeneity
2014, IcarusCitation Excerpt :As molecular abundances in comets are typically calculated with respect to H2O, it is desirable to have observations of H2O to compare to our derived molecular production rates. H2O does not have any transitions in the optical, but our bandpass includes the [O I]6300 Å line, which has been used as a reliable proxy for H2O production in the past (Spinrad, 1982; Magee-Sauer et al., 1990; Schultz et al., 1992; Morgenthaler et al., 2001; Morgenthaler et al., 2007; McKay et al., 2012). We employ the same Haser Model for the [OI] emission as used in McKay et al. (2012) to infer H2O production rates from our [OI] observations.
Observations of the forbidden oxygen lines in DIXI target Comet 103P/Hartley
2013, IcarusCitation Excerpt :The radiative decay results in spectral lines at 2972 and 5577 Å (1S) and at 6300 and 6364 Å (1D). Past studies have used [O I]6300 emission to obtain indirect estimates of the H2O production rate for many comets (Spinrad, 1982; Magee-Sauer et al., 1990; Schultz et al., 1992; Morgenthaler et al., 2001, 2007). If the green line at 5577 Å is also observed, then information about the parentage of the atomic oxygen can be obtained.
