The direct detection of gravitational waves (GW) from neutron stars (NS) has opened up a new window to explore properties of dense nuclear matter beyond the scope of terrestrial experiments. While signals from binary NS mergers have been analysed in great detail, another possibility to probe their composition and properties is via NS asteroseismology. However, it is crucial and timely to study these oscillation modes within different nuclear frameworks to avoid inaccurate interpretation of GW data. In this talk, we present our detailed investigations of f-modes within a phenomenological relativistic mean-field (RMF) model, for different composition in the NS interior. We perform a comparison of our results with those from the meta-model in order to probe any dependence on the underlying nuclear model. We also investigate, for the first time, the f-mode oscillations of neutron stars within the quark–meson coupling (QMC) model, including hyperons and H-dibaryons.
Universal relations are examined and compared with those in the existing literature for potential applications in GW asteroseismology.
