Scientific paper

Many extrasolar planets orbit very close to their parent star, so that they experience strong tidal interactions; by converting mechanical energy into heat, these tides contribute to the dynamical evolution of such systems. This motivates us to seek a deeper understanding of the processes that cause tidal dissipation, which depend both on the internal structure and the physical properties of the considered bodies. Here, we examine the equilibrium tide, i.e. the hydrostatic adjustment to the tidal potential, in a rotating fluid planet or star. We derive the adiabatic velocity field induced by the tidal perturbation and discuss in particular how the quality factor Q characterizing the dissipation is linked whith the turbulent viscosity of convection zones. Finally, we show how the results may be implemented to describe the dynamical evolution of the system.
