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.
