Model Description

Consider an asteroid belt surrounding a star. If a pulsar passes through this system, it is likely to encounter multiple asteroids. When this happens, charged particles may be stripped from the asteroidal surface into the NS magnetosphere, where they are accelerated to ultra-relativistic speeds, resulting in coherent curvature radiation.

Observational Constraints

The time between edge on collisions within the asteroid belt is consistent with the time between the signals of FRB 121102.
