Gravitational wave asteroseismology of dark matter hadronic stars

Abstract

The influence of the dark matter mass~($M_{\chi }$) and the Fermi momentum~($k_F^{\text{dm}}$) on the $f_0$-mode oscillation frequency, damping time parameter, and tidal deformability of hadronic stars are studied by employing a numerical integration of hydrostatic equilibrium, nonradial oscillation, and tidal deformability equations. The matter inside the hadronic stars follows the NL3* equation of state. We obtain that the influence of $M_{\chi }$ and $k_F^{\text{dm}}$ is observed in the $f_0$-mode, damping tome parameter, and tidal deformability. Finally, the correlation between the tidal deformability of the GW$170817$ event with $M_{\chi }$ and $k_F^{\text{dm}}$ are also investigated.
