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

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.

Automated summary

This paper investigates the effects of dark matter on neutron stars by utilizing a DM-admixed model. The Brueckner-Hartree-Fock theory, combined with realistic three-body forces and a generic bosonic self-interacting dark matter model, is used to describe the equations of state for nuclear matter and dark matter, respectively. The study focuses on the complete set of stable 'dark' neutron stars and particularly the observable radii of these objects. A diverse range of stellar configurations is discovered and extensively discussed.
