Model Description
Akin to SGRs powered by the release magnetic energy stored in magnetars, FRBs may be powered by the release of electrostatic energy stored in pulsars. Provided there are regions of magnetospheric plasma with distinct energy, separated by a vacuum gap, the discharge of such energy could manifest as “pulsar lighting”, analogous to the flow of current in the atmosphere when lightning strikes. This intense, rapidly varying, electric field in the gaps would accelerate electrons and positrons in the magnetosphere, producing coherent curvature radiation observable as an FRB.
