We discuss the dependence of the pulsation frequencies of the axial quasi-normal modes of a nonrotating neutron star upon the equation of state describing the star interior. The continued fraction method has been used to compute the complex frequencies for a set of equations of state based on different physical assumptions and spanning a wide range of stiffness. The numerical results show that the detection of axial gravitational waves would allow to discriminate between the models underlying the different equation of states, thus providing relevant information on both the structure of neutron star matter and the nature of the hadronic interactions.

  1. Dynamical system approach to the spectral (in)stability of black holes under localised potential perturbations

    gr-qc 2026-01 conditional novelty 7.0 of 10

    Black-hole resonances migrate along complex-plane flow lines toward hard-wall attractors, and repellers near the unperturbed modes explain why perturbation theory fails so early.

  2. Combining simulation-based inference and universal relations for precise and accurate neutron star science

    gr-qc 2026-01 conditional novelty 6.0 of 10

    A machine-learning simulator trained on 1,491 simulated equations of state discovers a neutron-star radius relation R(M,f,p1), predicting radii to tens of meters with calibrated error bars.

  3. Nonradial oscillations of realistic anisotropic neutron stars: Axial modes

    gr-qc 2026-05 unverdicted novelty 5.0 of 10

    Axial modes of anisotropic neutron stars show mass-scaled frequency and damping time with nearly universal quadratic dependence on compactness, insensitive to EOS and anisotropy model.

  4. Axial $w$-modes of anisotropic neutron stars

    gr-qc 2026-05 unverdicted novelty 4.0 of 10

    Axial w-mode frequencies of anisotropic neutron stars decrease monotonically with mass, depend approximately linearly on compactness with anisotropy modifying slope and intercept, damping times increase with mass, and...

  5. 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.
