Cooling of hadronic stars with dark matter components

Neutron stars, due to their extreme densities and pressures, act as unique laboratories for the study of dense matter. Recent research has introduced the notion of dark matter (DM) particles being part of neutron stars' composition, thus providing a novel path for investigating this mysterious universe component. This research builds on previous studies and shifts the focus towards exploring the effects of DM mixed with hadrons on the thermal evolution of stars. It involves analyzing the cooling curves of these stars and matching them with observed data from thermally emitting compact objects. This study will demonstrate that, despite being thermally inert, DM as postulated in this model can indirectly influence the thermal evolution of neutron stars. It will be illustrated that DM has the potential to modify the thermal relaxation time and expand the range of temperatures that neutron stars of various masses can exhibit. Through this comparative analysis, the model's precision will be evaluated, and the properties of DM particles will be further delineated. The goal of this study is to deepen our comprehension of neutron stars and the influence of DM on their thermal evolution.
