Abstract
We describe a generalization of the asymptotic calculation of the tida l torques experienced by a massive star as a result of a companion in circular orbit, originally considered by Zahn, to the case of a rotati ng star when the forcing frequency is small and in the inertial regime , that is it is less than twice the rotation frequency in magnitude, T he results confirm the presence of a strong toroidal mode resonance fe ature for retrograde forcing and also, with a simple description of th e convective core, the presence of some core inertial mode features in the response. These were found numerically by Savonije & Papaloizou.
