Gravitational wave background from neutron star phase transition

Abstract

We study the generation of a stochastic gravitational wave (GW) background produced by a population of neutron stars (NSs) which go over a hadron-quark phase transition in its inner shells. We obtain, for example, that the NS phase transition, in cold dark matter scenarios, could generate a stochastic GW background with a maximum amplitude of $h_{\mathrm{BG}}\sim 10^{-24}$, in the frequency band ${\nu }_{\mathrm{obs}}\simeq 20-2000\mathrm{Hz}$ for stars forming at redshifts of up to $z\simeq 20.$ We study the possibility of detection of this isotropic GW background by correlating signals of a pair of Advanced LIGO observatories.
