Frequencies of f - and p -oscillation modes in cold and hot compact stars (original) (raw)

This study employs a broad range of equations of state (EOSs) based on covariant density functional theory to analyze the polar f- and p-oscillation modes in cold and hot compact stars. By investigating the correlations between oscillation frequencies and global star parameters under varying conditions—including temperature effects and the influence of exotic particles—it reveals that finite temperature decreases oscillation frequencies in nucleonic stars. For stars incorporating exotic particles, higher oscillation frequencies are observed. This research enhances the understanding of neutron star characteristics and the underlying dense matter equation of state.
