"Differentially rotating neutron stars : A perturbative study"

A. Stavridis

We will present a study of non axisymmetric oscillations of differentially rotating neutron stars in the perturbative framework of General Relativity. Differential rotation plays an important role in nascent neutron stars, and recent numerical studies have shown that it can be responsible for an instability at low values of the ratio T/W. We study the oscillation spectrum of those stars and we investigate the possible effect of the existence of the corrotation band to the low T/W instability.
