Abstract

The CoRoT space mission is detecting every semesters several tens of exoplanets transiting candidates. Among this candidates, there are several background eclipsing binairies. The radial velocity follow-up, performed with the high-resolution spectrographs HARPS (3.6m ESO) and SOPHIE (1.93m OHP), consists to measure the mass of companions and allows to characterize the nature of transiting object. For the faintest target (14<mv<16) observed at low S/N, the moon background light may affect the spectra and introduce systematic errors in the Radial Velocity measurements. We studied the influence of this effect and optimized the data reduction pipeline in order to minimize it.
