Title: The r-mode spectrum of relativistic neutron stars
Author(s): J. Ruoff, K. Kokkotas (Oral)
ABSTRACT
I will present recent results on both time evolutions
and mode calculations of perturbations of slowly rotating relativistic
stars. I will mainly focus on the axial r-modes, where I show that at
least to linear order in the rotation rate, r-modes do not exist for
certain stellar models, quite in contrast to Newtonian predictions. In
those cases where the r-modes exist, the growth times predicted by fully
relativistic calculations agree very well with the Newtonian estimates.
