Abstract This project has the objective to study the tidal evolution of exoplanetary systems and their host stars, where tidal interactions are taken into account mainly in the frame of the creep tide theory. The variety of discovered exoplanetary systems up to this year shows that there are many possibilities for the planetary internal structure, compositions and orbital configurations of the exoplanetary systems (e.g from Kepler data). In what concerns this field of research, tidal interactions were already shown to play an important role on both the orbital and rotational evolution. Moreover, the current and future configuration of the rotation and the orbit of these systems are affected by: (i) the internal structure of the bodies, (ii) their composition, and (iii) the stellar evolution processes such as core-mantle coupling and tidal inertial waves. These are the gauges ruling how bodies respond to tidal stress, thus influencing the subsequent orbital and rotational evolution of the system. Thus, we propose an extension of the creep tide theory taking into account the processes of stellar evolution, which influence the effective viscosity of the star, as well as its radius. (AU) | |
