On the r-mode spectrum of relativistic stars: Inclusion of the radiation reaction
Johannes Ruoff, Kostas D. Kokkotas
We consider both mode calculations and time evolutions of axial r-modes for relativistic uniformly rotating non-barotropic neutron stars, using the slow-rotation formalism, in whic…

On the r-mode spectrum of relativistic stars in the low-frequency approximation
Johannes Ruoff, Kostas D. Kokkotas
The axial modes for non-barotropic relativistic rotating neutron stars with uniform angular velocity are studied, using the slow-rotation formalism together with the low-frequency…

The close-limit approximation to Neutron Star Collisions
G. D. Allen, N. Andersson, K. D. Kokkotas +3
We develop a close-limit approximation to the head-on collision of two neutron stars similar to that used to treat the merger of black hole binaries . This approximation can serve…
