Selection of most promising CoRoT candidates for radial-velocity follow-up

We used the method of Silva & Cruz (2006), which distinguishes between planetary and stellar companions by fitting transit light curves, to select the most promising CoRoT candidates to be monitored with radial-velocity measurements. Testing this method on the light curves of confirmed CoRoT exoplanetary systems shows that the estimated radius for such planets is smaller than 2RJup , while for most of the light curves in which no planet has been detected, the secondary companion has an estimated radius larger than 2RJup. We present preliminary results concerning other light curves for which no planet has been detected yet.
