Catalog of Cataclysmic Variables Around the Period-bounce: New Systems.

MUNOZ-GIRALDO D., STELZER B. and SCHWOPE A.

Abstract (from CDS):

A large portion of cataclysmic variables (CVs), between 40% and 80%, are predicted to be in the last stage of their evolution, becoming period-bouncers. This sub-class of CVs is characterized by having gone through a reversal in the evolution of their orbital periods as well as having a late-type donor. The large predicted population of period-bouncers has, however, not been observed so far. We have led an effort to reveal the missing population of period-bouncers though the use the X-ray survey eROSITA, which has increased the population of period-bouncers by 63% through the use of eROSITA. This study has established eROSITA as a promising path for the identification of the new members of this underrepresented sub-class of CVs.
