Gravitational waves from neutron stars described by modern EOS

TL;DR

This paper computes neutron star oscillation frequencies and damping times using modern equations of state, revealing that existing empirical relations need updates to accurately connect these properties with star mass and radius.

Contribution

It provides updated calculations of neutron star oscillation properties based on recent equations of state, challenging previous empirical relations.

Findings

Some empirical relations between oscillation modes and star properties need modification.

Abstract

The frequencies and damping times of neutron star (and quark star) oscillations have been computed using the most recent equations of state available in the literature. We find that some of the empirical relations that connect the frequencies and damping times of the modes to the mass and radius of the star, and that were previously derived in the literature need to be modified.
