Impacts of Dark Matter on Thermal Emission of Neutron Star

We investigate the potential indirect consequences of captured dark matter on the cooling process of neutron stars (NSs). Employing the relativistic mean-field formalism with the IOPB-I parameter set [6], we derive the equation of state (EOS) for different dark matter admixed star configurations at a fixed temperature of \(10^{9}\,K\) . Through our analysis, we demonstrate that the variation in dark matter momentum has a significant impact on the neutrino emissivity, specific heat, and thermal conductivity of the star. We have also examined the relationship between the equation of state, chemical composition of stellar matter, and the surface thermal emission. Our analysis has led us to conclude that increasing the dark matter component led to a fast cooling scenario and enhanced internal relaxation rates of the NS.
