A photometric study of the cataclysmic variable, LX Serpentis.
Abstract
A high-speed photometric study of the cataclysmic variable star LX Serpentis has been performed, using a 1.2 m synoptic telescope in white light. By means of a second-order least squares fitting of the eclipse times, an orbital period of about 0.158 hr was derived. The shapes of the eclipse light curves indicate that the hot-spot brightness morphology can be irregular, and it can change in a time scale of days. An analysis of the power-spectrum reveals a low signal-to-noise ratio peak at about 0.007 Hz (about 140 sec), but in general no evidence was found for periodic or quasi-periodic oscillations in the power spectrum.
