Gravitational wave asteroseismology of fast rotating neutron stars with realistic equations of state
Daniela D. Doneva, Erich Gaertig, Kostas D. Kokkotas +1
In the present paper we study the oscillations of fast rotating neutron stars with realistic equations of state (EoS) within the Cowling approximation. We derive improved empirical…
Gravitational wave asteroseismology with fast rotating neutron stars
Erich Gaertig, Kostas D. Kokkotas
We investigate damping and growth times of the f-mode for rapidly rotating stars and a variety of different polytropic equations of state in the Cowling approximation. We discuss t…
Oscillations and instabilities of fast and differentially rotating relativistic stars
Christian Krüger, Erich Gaertig, Kostas D. Kokkotas
We study non-axisymmetric oscillations of rapidly and differentially rotating relativistic stars in the Cowling approximation. Our equilibrium models are sequences of relativistic…
Relativistic g-modes in rapidly rotating neutron stars
Erich Gaertig, Kostas D. Kokkotas
We study the g-modes of fast rotating stratified neutron stars in the general relativistic Cowling approximation, where we neglect metric perturbations and where the background mod…
Oscillations of rapidly rotating relativistic stars
Erich Gaertig, Kostas D. Kokkotas
Non-axisymmetric oscillations of rapidly rotating relativistic stars are studied using the Cowling approximation. The oscillation spectra have been estimated by Fourier transformin…
