Descripción
Deviations from strict periodicity of eclipsing binary minimum times have long been known to be caused by the presence of additional bodies near the system. Giant plan- ets orbiting around both binary components would add a beat frequency to observed minimum times, given by their orbital period. For low-mass eclipsing binary systems, such timing deviations may be as large as a few seconds from orbiting Jupiter mass planets. We present the status of an observing program that has been surveying several short periodic eclipsing binaries since 1996. Future space based missions (COROT, Eddington, Kepler) aimed at the detection of planetary transits will give a greatly extended sample of precise minimum times. All these mission will perform extended high precision photometric surveys of large stel- lar fields, which are expected to contain hundreds of eclipsing binaries whose min- imum times may be analyzed. We estimate the range of detections of non-transiting planets around binaries that may be achievable with these missions.
