A Spectroscopic Study of HL Canis Majoris
arXiv:astro-ph/0506068 · doi:10.1086/430805
Abstract
We present optical spectroscopy of the dwarf nova HL Canis Majoris over a span of four years. The observations were made during standstill, outburst, and quiescence. We determine an orbital period of 0.2167867 +/- 0.0000017 days, based on radial velocities determined from H-alpha, H-beta, and He I 5876 emission. We also present equivalent widths of the spectral features in outburst and in quiescence.
