The stochastic background of gravitational waves due to the f-mode instability in neutron stars
Marco Surace, Kostas D. Kokkotas, Pantelis Pnigouras
This paper presents an estimate for the spectral properties of the stochastic background of gravitational waves emitted by a population of hot, young, rapidly rotating neutron star…
A gravitational wave afterglow in binary neutron star mergers
Daniela D. Doneva, Kostas D. Kokkotas, Pantelis Pnigouras
We study in detail the f-mode secular instability for rapidly rotating neutron stars, putting emphasis on supermassive models which do not have a stable nonrotating counterpart. Su…
Saturation of the f-mode instability in neutron stars: I. Theoretical framework
Pantelis Pnigouras, Kostas D. Kokkotas
The basic formulation describing quadratic mode coupling in rotating Newtonian stars is presented, focusing on polar modes. Due to the Chandrasekhar-Friedman-Schutz mechanism, the…
