On the Tidal Interaction of a Solar‐Type Star with an Orbiting Companion: Excitation of<i>g</i>‐Mode Oscillation and Orbital Evolution

We calculate the dynamical tides raised on a nonrotating solar-type star by a close stellar or planetary companion. Dissipation arising from a turbulent viscosity operating in the convection zone and radiative damping in the radiative core are considered. We compute the torque exerted on the star by a companion in …
