Model Description
FRBs may be the result of short bursts created in the closed field line regions of magnetar magnetospheres (as opposed to near the caps as in pulses). Crustal slippage on the surface of the magnetar causes magnetic reconnection and thus particle acceleration, producing coherent emission.
