1995PASP..107..931H

A new close binary containing a DA white dwarf and a dwarf M star has been identified from its X-ray emission. The spectra of both stars are seen with about equal flux at ∼4600A. H and Ca II emission, associated with the M star, is also present. Limited photometry does not show any variability, but radial velocity changes indicate the binary period lies in the range from ∼0.7 to a few days. The small observed velocity range and lack of pronounced emission line changes suggest a low inclination system. The DA velocities are poorly determined but suggest the unlikely conclusion that it may be the less massive star in the binary.
