Galactic dark matter (DM) particles, having non-gravitational interactions with nucleons, can interact with stellar constituents and eventually become captured within stars. Over the lifetime of the celestial body, these non-annihilating,…
Dark matter from the galactic halo can accumulate in neutron stars and transmute them into sub-2.5 $M_{\odot}$ black holes if the dark matter particles are heavy, stable, and have interactions with nucleons. We show that non-detection of…
