Abstract
We investigate the dark matter impact on properties of strange quark stars, such as mass-to-radius profiles and oscillation radial modes. The dark matter particle may be a boson or a fermion. First, in the two-fluid formalism we integrate the structure equations to obtain the interior solution. Next, this solution is plugged into the equations for the perturbations to obtain the frequency radial modes and the corresponding eigenfunctions. The large separation, a good observational signature, is also computed. Author will discuss radial oscillations of neutron stars with an accurate equation-of-state without dark matter.
