Transit timing variation and activity in the WASP-10 planetary system
Original language description
Transit timing analysis may be a method of discovering additional bodies in extra- solar systems that harbour transiting exoplanets. The deviations from the Keplerian motion, caused by mutual gravitational interactions between planets, are expected to generate transit timing variations of transiting exoplanets. In 2009, we collected nine light curves of eight transits of the exoplanet WASP-10b. Combining these data with those published, we have found that transit timing cannot be explained by a constantperiod but by a periodic variation. Simplified three-body models, which reproduce the observed variations of timing residuals, were identified by numerical simulations. We have found that the configuration with an addi- tional planet with a mass of 0.1MJ and an orbital period of 5.23 d, located close to the outer 5:3 mean motion resonance, is the most likely scenario. If the second planet is a transiter, the estimated flux drop will be 0.3 per cent and can be observed with a ground-bas
