MULTI-PERIOD G-MODE PULSATIONS OF A PRE-HE-WD STAR IN THE ECLIPSING BINARY KIC 9164561

ABSTRACT We report the discovery of a new pulsating pre-He-WD in the EL CVn-type binary KIC 9164561. Light curve modeling and frequency analysis of the binary system were carried out based on short-cadence Kepler photometry. Combined with the radial-velocity solution, revised physical parameters of...
