LX Ser

An Eclipsing Cataclysmic Variable Star

LX Serpentis(LX Ser) is a deeply eclipsing cataclysmic variable star with an orbital period of 0.1584325d and located in the constellation Serpentis.LX Ser was first identified to be an eclipsing CV by Stepanian (1979) while searching galaxies with ultraviolet continuum and was classified to be SW Sex subclass of CVs. Stepanian (1979) found that the brightness of LXSer was about mV = 14mag.Recently, the orbital inclination and mass ratio of LX Ser were determined to be i = 79.◦0 and q = 0.50 by Marin, Shafter, and Misselt (2007).
