We investigate inertial mode oscillations of slowly and uniformly rotating, isentropic, Newtonian stars. Inertial mode oscillations are induced by the Coriolis force due to the star's rotation, and their characteristic frequencies are comparable with the rotation frequency Ω of the star. So-called r-mode oscillations form a subclass of the inertial modes. In this paper, we use the term "r-modes" to denote the inertial modes for which the toroidal motion dominates the spheroidal motion, and the… Expand
