Multimessenger and astrophysics probes of dark matter 3

The capture of Dark Matter in Neutron Stars has garnered considerable interest in recent years. This interest is driven by the prospect that the energy deposited by dark matter scattering can heat these objects to infra-red temperatures, which may soon be within reach of observations. In order to obtain reliable results from these searches, proper incorporation of the physics of Neutron stars...
Neutron star (NS) as the dark matter (DM) probe has gained a broad attention recently, either from heating due to DM annihilation or its stability under the presence of DM. In this work, we investigate spin-$1/2$ fermionic DM $\chi$ charged under the $U(1)_{X}$ in the dark sector. The massive gauge boson $V$ of $U(1)_{X}$ gauge group can be produced in NS via DM annihilation. The produced...
We discuss the capture of dark matter in white dwarfs (WD), the most abundant stellar remnants, as complimentary to terrestrial searches. We consider the capture of DM due to interactions with either ion or the degenerate electron component of WDs. For the discussion of the capture rate we account for the stellar structure, the star opacity, realistic nuclear form factors and temperature...
