Constraint on Dark Matter Using Neutron Stars

Abstract

In this study, the nature and properties of dark matter are explored with the help of neutron stars. Dark matter is assumed to have a particle nature, and different dark matter candidates are considered and tested using neutron stars. If neutron stars capture dark matter from the halo, their properties must change, with various candidates affecting them in different ways. Based on these changes, the nature of dark matter is studied, and possible directions for future studies are explored. In addition to dark matter capture, the recent hypothesis concerning the possible decay of neutrons into dark matter, as suggested by Fornal and Grinstein, and Strumia, is thoroughly studied. Constraints on the properties of dark matter have been established, and observable signals from neutron stars are suggested. Using neutron star cooling, possible decay modes of dark bosons into Standard Model particles are also investigated.
