Description
I will discuss dark matter neutron stars in a class of models where the dark sector is a copy of the Minimal Supersymmetric Standard Model, but with the important difference that the dark supersymmetry-breaking scale is much higher than in the visible sector. This scenario allows the dark quark mass hierarchy to be different from the visible sector, resulting in a stable dark neutron which can play the role of cold dark matter on large scales at late times, while dark dissipative cooling allows additional early collapse of overdensities on small scales. At late times these become either small black holes or dark neutron stars. There are possibilities for detection of a visible luminosity due to kinetic mixing between the dark and visible photons, in addition to gravitational microlensing.
