HS 2325+8205

An Eclipsing Cataclysmic Variable Star

HS 2325+8205 is an eclipsing cataclysmic variable star of the dwarf nova type. The system consists of a white dwarf accreting matter from a donor star via an accretion disk. HS 2325+8205 exhibits recurrent outbursts typical of dwarf novae, along with eclipses observable during both quiescence and outburst states. Its orbital period is about 4.65 hours, placing it just above the so-called "period gap." The system is of interest for studying accretion disk evolution, eclipse behavior, and the dynamics of variable close binary stars.
