Two—Color V and R CCD Photometry of the SW Sex—Type Eclipsing Cataclysmic Variable V1315 Aql

摘要

The V-R color index shows a complicated behaviour during the eclipse, being largest at the brightness minimum, but showing asymmetric min-ima at phases -0.07 and +0.13. The hump at the light curve occurs after the eclipse, contrary to systems with the "hot spot". The phases of minima in V and R are 0.0092(17) and 0.0062(17), respectively, for the mean date JD=2453202.
