The Dark Side of Neutron Stars

Research output: Contribution to journalJournal articleResearchpeer-review


We review severe constraints on asymmetric bosonic dark matter based on observations of old
neutron stars. Under certain conditions, dark matter particles in the form of asymmetric bosonic
WIMPs can be eectively trapped onto nearby neutron stars, where they can rapidly thermalize and
concentrate in the core of the star. If some conditions are met, the WIMP population can collapse
gravitationally and form a black hole that can eventually destroy the star. Based on the existence
of old nearby neutron stars, we can exclude certain classes of dark matter candidates.
