Scientific paper

We briefly review recent simulations of pulsations in rotating relativistic stars, obtained with several different numerical codes in various approximations: the Cowling approximation and the conformally flat (CFC) approximation for fluid pulsations and the inverse Cowling approximation for spacetime pulsations. We discuss the eigenfrequencies of the most important axisymmetric modes of uniformly and differentially rotating stars and their avoided crossings and possible nonlinear couplings. Another nonlinear effect that was found recently to operate for very rapid rotation is the mass-shedding-induced damping of pulsations. This effect may have implications for the gravitational-radiation-driven f-mode instability. The review closes with a discussion of the effort of extending gravitational wave asteroseismology to rapidly rotating proto-neutron stars.
