The photometric space-borne survey missions CoRoT and Kepler were designed mainly to discover transiting planets. However, they are capable of much more. Thousands of eclipsing binaries were detected in their lightcurves. In addition, using a novel method named BEER, non-eclipsing stellar binaries and even lower mass companions were detected.
In this talk I will review shortly the BEER algorithm, which identifies the periodic lightcurve modulation caused by the combined Beaming, Ellipsoidal, and Reflection effects induced by short-period companions. A summary of the ground-based radial velocity follow-up campaign will be given, as well as the discovery census. A special attention will be given to the hot Jupiter Kepler-76b, discovered with BEER.
To demonstrate also the potential of the not yet fully exploited sample of CoRoT eclipsing binaries, I will present the case of CoRoT 101186644: A transiting low-mass dense M-dwarf on an eccentric 20.7-day period orbit.
