In our previous paper, we found thatthe transit timing variations could be caused by the presence of a stellar companionin this system. Our main motivation for this paper was to investigate variation in aradial-velocity curve generated by this additional star in the system. We performedspectroscopic observation of Kepler-410 using three telescopes in Slovakia and CzechRepublic. Using the cross-correlation function, we measured the radial velocities of thestar Kepler-410A. We did not observe any periodic variation in a radial-velocity curve.Therefore, we rejected our previous hypothesis about additional stellar companionin the Kepler-410 system. We ran different numerical simulations to study mean-motion resonances with Kepler-410Ab. Observed transit timing variations could bealso explained by the presence of a small planet near to mean-motion resonance 2:3with Kepler-410Ab. This resonance is stable on a long-time scale. We also looked forstable regions in the Kepler-410 system where another planet could exist for a longtime. ER -
