Interplay between planets and host stars

M. Bazot

Abstract.
With the incresing number of planet discovery, we are starting to observe potential manifestations of their interaction with their host-stars. In this presentation I give an overview of the interplays that might be at work in the planet-star couple. I present the basic ideas concerning accretion on main-sequence and red-giant stars. I also discuss briefly the possibility of tidally-induced coupling between planet orbital dynamics and stellar pulsations. In each case I focus on how we can improve our understanding of these problem through the use of asteroseismology.
