We study the problem of detecting, and infering astrophysical information from, gravitational waves from a pulsating neutron star. We show that the fluid f and p-modes, as well as the gravitational-wave w-modes may be detectable from sources in our own galaxy, and investigate how accurately the frequencies and damping rates of these modes can be infered from a noisy gravitational-wave data stream. Based on the conclusions of this discussion we propose a strategy for revealing the supranuclear equation of state using the neutron star fingerprints: the observed frequencies of an f and a p-mode. We also discuss how well the source can be located in the sky using observations with several detectors.

  1. Magnetic effects on fundamental modes in rotating neutron stars with a purely toroidal magnetic field

    astro-ph.HE 2025-09 conditional novelty 6.0 of 10

    Even with both rotation and a toroidal magnetic field, neutron star fundamental-mode frequencies stay quasi-linear in compactness and T/|W|, with magnetization-dependent slopes, and the f_2f/f_F ratio can help constra...

  2. Effect of Dark matter and $\sigma$-cut potential on radial and non-radial oscillation modes in neutron stars

    astro-ph.HE 2025-07 conditional novelty 4.0 of 10

    Dark matter-admixed neutron stars oscillate at higher f- and p1-mode frequencies than ordinary or σ-cut models, while quasi-universal oscillation relations still hold.
