New Eclipsing Cataclysmic Variable Candidate in the Period Gap
Abstract
We report the discovery of a blue eclipsing variable Dan V1 in Sagittarius with the orbital period P=0.094277 d (2.2626 h). The object is also an UV source, indicating the presence of a white dwarf in the binary system. We consider two possibilities: a cataclysmic (nova-like) variable and an eclipsing hot subdwarf of the HW Vir type. Our analysis favors the first (CV) scenario. If confirmed, Dan V1 is a very rare eclipsing cataclysmic variable in the period gap.
