Mar. 07/12/2021 14:00 Grande Ourse, Bâtiment 13, Etage 1 AMARD Louis (CEA - Laboratoire AIM) The evolution of young stars : focus on rotation and activity (Astrophysique Stellaire) Between its formation stage as an active accreting seed and today, the Sun underwent large structural changes as well as variation in magnetic activity, rotation rate and its relation to the surrounding environment. I will go through the different processes that are responsible for these changes and present our latest results on the subject. We will go from the early interaction between the star and its proto-planetary disc bathing in UV radiations emitted from the massive neighbours, to the internal mixing happening in the inner layers of solar-like stars and probed by asteroseismology.
