Model Description
Upon the collapse of a supramassive NS into a NKBH, an event horizon will likely form before most of the mass and radiation can escape. By the no-hair theorem, magnetic fields are forbidden from piercing the event horizon, and so the magnetosphere will be left behind. Alternatively, if a NS collapses into a metastable KNBH, its electric discharge can cause the magnetosphere to be shed. Violent magnetic reconnection outside the horizon would then induce a strong magnetic shock wave that moves through the remaining plasma at the speed of light, resulting in a single FRB.
