Transit Time Variation in CoRoT planetary systems
J. Korth, S. Grziwa, M. Pätzold


Transit Time Variation (TTV) are the earlier or later occurrence of a planetary transit relative to the time of a reference transit and can easily be detected in stellar light curves. TTV may arise by the gravitational perturbation of the transiting planet by another or more still undetected planet(s) in the same stellar system and is therefore prove for the existence of further planets. The derivation of the orbital parameters of the undetected planet(s) is, however, constrained by the magnitude of the TTV. We examine CoRoT light curves for the existence of TTV.
