Since gamma radiation provides the energy preventing gravitational collapse of the outer layers of the star onto the core, at some point the loss of this energy (through so - called «pair instability») causes violent pulsations that eject a large fraction of the outer layers of the star and eventually a star's outer layers to collapse inward to create a thermonuclear explosion that, in theory, would be brighter than previously detected supernova.
