V 1315 Aql

An Eclipsing Cataclysmic Variable Star

V1315 Aql is a nova-like cataclysmic variable star of the SW Sextantis subtype, located in the constellation Aquila. It is a close binary system where a white dwarf accretes material from a donor star-typically a red dwarf-via an accretion disk. V1315 Aql exhibits partial eclipses, strong emission lines in its spectrum, phase lags, and other features typical of SW Sex stars. Its orbital period is approximately 3.35 hours, placing it within the range of most SW Sextantis systems. V1315 Aql is frequently studied in the context of accretion physics and magnetic effects in cataclysmic variables.
