Description
We investigate the effect of dark matter components inside a neutron star using gravitational wave constraints coming from a binary neutron star merger. We study fermionic dark matter interacting with nucleonic matter via the Yukawa interaction inside the neutron star, as well as, density-dependent dark matter components
inside neutron stars. We argue that the admixture of dark matter inside the neutron star significantly affects the neutron star equation state, mass-radius, and tidal deformability. Gravitational-wave observation GW170817 puts a constraint on the upper bound on the tidal deformability of a binary neutron star. Such
gravitational wave observation puts a stringent constraint on the nuclear equation of state. We investigate any physical implication of such an observational constraint coming from the gravitational wave observation on the dark matter admixed neutron stars. We argue that in the presence of a dark matter component even the stiff equation of state can satisfy tidal deformability bound coming from the gravitational wave observation.
