From angular momentum to tidal interaction : a journey with the rotation

Florian Gallet (Université de Genève)
Thursday November 3rd - 11am
IPAG Seminar Room - IPAG

The number and quality of the stellar and planetary measurements has continuously increased during the last two decades. To account for the complex patterns and features that we start to distinguish in these observations, we now need to go one step forward in stellar and planetary numerical codes by including the interaction between a rotating star and its orbiting planet(s). Indeed, stellar surface rotation rate and planetary orbital radius are both directly affected by such interaction. In this presentation I will show you that stellar rotation must be included in almost all physical mechanisms involving either a lonely star or a star-planet system, from the stellar angular moment evolution up to the dissipation of tidal waves inside the convective envelope of a star, and that rotation could also play an indirect role, through the stellar dynamo/activity, in planetary habitability.
