Query: Dark Matter Mini-halo around the Compact Objects: the Formation,
  Evolution and Possible Contribution to the Cosmic Ray Electrons/Positrons   Dark matter particles may be captured by a star and then thermalized in the
star's core. At the end of its life a massive star collapses suddenly and a
compact object is formed. The dark matter particles redistribute accordingly.
In the inelastic dark matter model, an extended dense dark matter mini-halo
surrounding the neutron star may be formed. Such mini-halos may be common in
the Galaxy. The electron/positron flux resulting in the annihilation of dark
matter particles, however, is unable to give rise to observable signal unless a
nascent mini-halo is within a distance \sim a few 0.1 pc from the Earth.
