Abstract

The great variety of exoplanetary systems discovered in the last few decades has revealed an incredible richness in their diversity, raising questions about the mechanisms driving their formation and evolution. Understanding these complex phenomena required the joint effort of the stellar and exoplanetary communities, given the key role played by the host star from the earliest stages, throughout the whole evolution of the system. Stars interact with their exoplanets through gravitation, radiation, magnetic fields, and stellar winds. All these interactions intimately depend on the structural and rotational properties of the host star, thus in order to account for their variations along the evolution of the system it is crucial to consider the evolution of the star. In this work, the impact of gravitational tidal and radiative interactions in the evolution of star-planet systems (Kepler-444, TOI-849, HD 29399, HD 22532, HD 64121, HD 69123, Kepler-93) is investigated.
