== Model Description ==

It is possible that a NS could capture ambient DM particles as they scatter off the NS nucleons and become gravitationally bound. Once the DM particles thermalize to the NS temperature, they sink to the center of the NS. Here they accumulate until they reach a critical mass and collapse into a BH. The BH will then engulf the NS, ejecting the NS magnetosphere, causing violent magnetic reconnection. The resultant coherent curvature radiation may be consistent with a single FRB.

== Observational Constraints ==

The lifetime of a NS undergoing DM-induced collapse is proportional to the density of DM in its local environment. In regions of low DM density, NS lifetimes are of the Hubble scale, however where the DM densities are high, the final NS collapse may be observable today. Origins are thus expected to be central regions of high density galaxies, {\it i.e.} massive spirals, early type galaxies, and central cluster galaxies.
