We present a new algorithm - BEER, to search for a combination of the
BEaming, Ellipsoidal and the Reflection/heating periodic modulations in
satellite light curves, induced by short-period non-transiting companions.
The beaming effect is due to the increase (decrease) of the brightness
of any light source approaching (receding from) the observer. To first
order, the beaming and the reflection/heating effects modulate the
stellar brightness at the orbital period, with phases separated by a
quarter of a period, whereas the ellipsoidal effect is modulated with
the orbital first harmonic.
The phase and harmonic differences between the three modulations
allow BEER to identify good candidates, using the precise lightcurves of
Kepler and CoRoT space missions.
We report on the confirmation of 30 newly discovered BEER binaries by
ground-based RV observations.
