Non-radial oscillations of neutron stars and the detection of gravitational waves

TL;DR

This paper investigates the non-radial oscillations, especially f-modes, of relativistic neutron stars and assesses their potential detectability via gravitational waves with the Mario Schenberg detector.

Contribution

It provides a comparison of neutron star f-mode frequencies with the sensitivity range of a specific gravitational wave detector.

Findings

f-mode frequencies are within the sensitivity range of Mario Schenberg

Relativistic effects influence the oscillation modes

Potential for gravitational wave detection from neutron star oscillations

Abstract

We study the non-radial oscillations of relativistic neutron stars, in particular the (fundamental) f-modes, which are believed to be the most relevant for the gravitational wave emission of perturbed isolated stars. The expected frequencies of the f-modes are compared to the sensitivity range of Mario Schenberg, the Brazilian gravitational wave spherical detector.
