Seventy new non-eclipsing BEER binaries discovered in CoRoT lightcurves and confirmed by RVs from AAOmega

preprint2015arXivOpen access

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 0.5−870.5-87 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 0.3−100.3-10 days.
