摘要：

A statistical study of solar-type stars for which superflares have been observed with the Kepler orbital observatory is presented. Methods developed for solving similar problems for flare stars are invoked to do this. The total number of stars capable of superflares is estimated and the flare frequency distribution is determined for the complete set of stars and for separate subsamples constructed by breaking the complete sample into two parts in terms of the rotation periods and variability amplitudes of the stars. The star KIC 7264976 is found to have a statistically significant variation in its frequency of superflares.
