Gravitational waves from freely precessing neutron stars
In this paper we model the gravitational wave emission of a freely precessing neutron star. The aim is to estimate likely source strengths, as a guide for gravitational wave astronomers searching for such signals. We model the star as a partly elastic, partly fluid body with quadrupolar deformations of its moment of inertia tensor. The angular amplitude of the free precession is limited by the ...
متن کاملGravitational Radiation from Mergers of Black Hole–neutron Star Binaries
Angular momentum loss via the emission of gravitational waves must eventually drive compact binaries containing black holes and/or neutron stars to coalesce. The resulting events are primary candidate sources for detectors such as VIRGO and LIGO. We present calculations of gravitational radiation waveforms and luminosities for the coalescence of a black hole-neutron star binary, performed in th...
متن کاملGravitational waves from the 3D collapse of a neutron star to a Kerr black hole
We present the gravitational waveforms emitted when a neutron star, modeled as an initially uniformly rotating polytrope, collapses to a Kerr black hole. We investigate the gravitational collapse by carefully studying not only the dynamics of the matter, but also that of the trapped surfaces, of both the apparent and event horizons formed during the collapse. The use of these surfaces, together...
متن کاملParameter Estimation on Gravitational Waves from Neutron-star Binaries with Spinning Components
Inspiraling binary neutron stars are expected to be one of the most significant sources of gravitational-wave signals for the new generation of advanced ground-based detectors. We investigate how well we could hope to measure properties of these binaries using the Advanced LIGO detectors, which began operation in September 2015. We study an astrophysically motivated population of sources (binar...
متن کاملProspects for gravitational-wave observations of neutron-star tidal disruption in neutron-star-black-hole binaries.
For an inspiraling neutron-star-black-hole (NS-BH) binary, we estimate the gravity-wave frequency f(td) at the onset of NS tidal disruption. We model the NS as a tidally distorted, homogeneous, Newtonian ellipsoid on a circular, equatorial geodesic around a Kerr BH. We find that f(td) depends strongly on the NS radius R, and estimate that LIGO-II (ca. 2006-2008) might measure R to 15% precision...
