Description
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.
