Outburst and Quiescence Observations of the Dwarf Nova V101 in the Globular Cluster M5
Abstract
The authors have observed the dwarf nova V101 towards the globular cluster M5 through most of an eruption, and during quiescence. Assuming it to be a member of the cluster, V101 reached MB ≅ +4.3 at maximum and MB ≡ +7.6 at minimum, in good agreement with determinations for field dwarf novae. The outburst rise and fall times and total duration imply a long orbital period (≡11 hr) and possibly an evolved secondary. This hypothesis is consistent with the red continuum of V101 seen in the spectrum of Margon et al. (1981).
