Abstract

We applied the BEER algorithm to the CoRoT lightcurves from the first five LRc fields and identified 481481 non-eclipsing BEER candidates with periodic lightcurve modulations and amplitudes of 0.5870.5-87 mmag. Medium-resolution spectra of 281281 candidates were obtained in a seven-night AAOmega radial-velocity (RV) campaign, with a precision of 1\sim1 km/s. The RVs confirmed the binarity of 7070 of the BEER candidates, with periods of 0.3100.3-10 days.
