Model Description

This model considers radial dark matter (RDM) stars - dark stars which are coupled to radial dark matter flows. These are kind of Planck star whose evolution has been halted by the pressure of dark matter flows surrounding the star. An FRB may be created when an asteroid falls onto the star: the large gravitational force in the RDM-star interior accelerates nucleons of the asteroid to extremely high energies. These collide with the core of the star, reacting with the Planck particles to create stimulated emission akin to an FRB.
