Resumen

The influence of the dark matter mass (Mχ) and the Fermi momentum (kFDM) on the f0-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 Mχ and kFDM is observed in the f0-mode, damping tome parameter, and tidal deformability. Finally, the correlation between the tidal deformability of the GW170817 event with Mχ and kFDM are also investigated.
