Dark Matter Seeding in Neutron Stars
  We present a mechanism that may seed compact stellar objects with stable
lumps of quark matter, or {\it strangelets}, through the self-annihilation of
gravitationally accreted WIMPs. We show that dark matter particles with masses
above a few GeV may provide enough energy in the nuclear medium for quark
deconfinement and subsequent strangelet formation. If this happens this effect
may then trigger a partial or full conversion of the star into a strange star.
We set a new limit on the WIMP mass in the few-GeV range that seems to be
consistent with recent indications in dark matter direct detection experiments.
