摘要: We present our results of study the oscillations and instabilities rapidly rotating relativistic stars in Cowling approximation. This is first its kind provides information on effect fast rotation oscillation spectra while it offers possibility studying complete problem by including spacetime perturbations. Our includes both axisymmetric non-axisymmetric perturbations limits for onset secular bar mode rotational instability. also approximate formulae dependence spectrum from rotation. The suggest that possible to extract star's parameters observed gravitational wave spectrum.
