Thanks to their extreme properties compact objects are efficient probes to unveil interactions between standard model and dark matter candidates. I will focus on the case of neutron stars (NS) and discuss two scenarios where either asymmetric DM particles or primordial black holes (PBH) get trapped by the stars. I will describe the peculiar interactions with the highly degenerate Fermi material of the NS, and the subsequent cataclysmic event where the NS is turned into a black hole. These scenarios promise new signatures, and I will highlight the novelties we have introduced as well as the stringent constraints we draw on the DM parameter space.
