WebSubsequently, the NITR model equation of state (EOS) is employed to obtain the properties of a dark matter admixed neutron star using two approaches: non-gravitational (single fluid) and two-fluid. In the two-fluid model, the dark matter (DM) particles only interact with each other via gravity rather than the nucleons.
