Model Description
In close analogy with the axion quark nugget (AQN) mechanism for generating solar nano flares, an AQN falling through an opportunely complicated region in a NS’s magnetosphere may be able to produce sufficient magnetic energy to power FRBs. Shock waves caused by the infalling AQN would trigger magnetic reconnection, and produce a giant flare.
Observational Constraints
There is a maximum cut-off frequency at infra-red wavelengths, and thus counterparts with higher frequencies would invalidate the model.
