  Asymmetric Dark Stars, i.e., compact objects formed from the collapse of
asymmetric dark matter could potentially produce a detectable photon flux if
dark matter particles self-interact via dark photons that kinetically mix with
ordinary photons. The morphology of the emitted spectrum is significantly
different and therefore distinguishable from a typical black-body one. Given
the above and the fact that asymmetric dark stars can have masses outside the
range of neutron stars, the detection of such a spectrum can be considered as a
smoking gun signature for the existence of these exotic stars.
