• D96, 063002(2017)., hereafter BDM17] extended the analytical formalism of dark matter (DM) capture in a very important way, which allows, in principle, the use of compact astrophysical objects, such as neutron stars (NS), as dark matter detectors.
• In this comment, we point out the existence of a region in the dark matter neutron scattering cross section $(\sigma_{nX})$ vs.
