Abstract

The influence of the dark matter mass~(MχM_{\chi}) and the Fermi momentum~(kF\dmk_{F}^{\dm}) on the f0f_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 MχM_{\chi} and kF\dmk_F^{\dm} is observed in the f0f_0-mode, damping tome parameter, and tidal deformability. Finally, the correlation between the tidal deformability of the GW170817170817 event with MχM_{\chi} and kF\dmk_F^{\dm} are also investigated.
