- We have investigated the transit timing variations (TTVs) induced by planetary tidal interactions. The main type of planets for which such effects could be observable are rocky super-Earths. For this study, we have included a recently-developed equilibrium tides model in a stable N-body code called Posidonius. An application to the super-Earth K2-265 b was considered. We have verified that tidally induced TTVs could be potentially observable especially in the case of non-synchronous spin-orbit resonant states for the planet. The spin-orbit resonance leading to the biggest TTV amplitudes is the 3:2 resonance, for which even a baseline of 2 years would be able to cause a TTV of some seconds in the case of a homogeneous K2-265 b on an eccentric orbit.
