Eigenmodes of axisymmetric neutron stars in relativistic perturbation theory — •Stratos Boutloukos — Universität Tbingen

We perform perturbation theory on rapid-rotating neutron stars by use of the relativistic Cowling approximation and compute their eigenfrequencies. We are able to calculate for the first time the complete spectrum of axissymetric oscillations, including, the important for gravitational-wave detection, r-modes. The frequency window is determined and various eigenfunctions are shown. The results are compared with previous studies.
