Dark matter effects on the properties of neutron stars: optical radii

Abstract

We study the effects of dark matter on the properties of neutron stars by employing a DM-admixed model. The Brueckner-Hartree-Fock theory with realistic three-body forces and a generic bosonic self-interacting dark matter model describe the equations of state for nuclear matter and DM, respectively. We study the complete set of stable dark neutron stars and in particular the observable radii of these objects. A rich variety of stellar configurations is found and discussed in detail.
