A New Cataclysmic Variable in Hercules
Abstract
We present time-series observations, spectra, and archival outburst data of a newly discovered variable star in Hercules, Var Her 04. Its orbital period, mass ratio, and outburst amplitude resemble those of the ugwz-type subclass of ugsu dwarf novae. However, its supercycle and outburst light curve defy classification as a clear ugwz. Var Her 04 is most similar to the small group of possible hydrogen-burning ``period bouncers,'' dwarf novae that have passed beyond the period minimum and returned.
