Stellar superflares. The top panel shows flare energy and the bottom panel shows the frequency of occurrence of flares per year per star versus the period of brightness variation (a proxy for stellar rotation period). These observations show that extremely strong superflares occur more frequently in faster rotating stars and that solar-like stars can in principle produce extremely strong, superflares.
