Connecting Algols To Cvs

Abstract

In this work, we review the evolutionary sequence of close binary systems, specifically the evolutionary sequence that connects Algols to Cataclysmic Variables. In support of this evolutionary sequence, we look for commonalities between Algols like β Per and Cataclysmic Variables with accretion disks. One dynamical activity that seems to be present in both is prograde disk precession, which generates positive superhumps in light curves. To this list of commonalities, we suggest retrograde precession and negative superhumps, and we look for signatures in the Kepler light curves of WX Draconis, an Algol system like β Per. From a comparison of light curves, we find that an accretion disk is likely present around the primary in WX Draconis. To generate the quasi-periodic long term modulation, this disk may be tilted and precessing in the retrograde direction.
