This enabled us to have a more well-established view on stat properties of superflares.', 'We updated the flare detection method from our previous studies by using high-pass filter to remove rotational variations caused by starspots. We also examined the sample biases on the frequency of superflares, taking into account gyrochronology and flare detection completeness.', 'The observed upper limit of the flare energy decreases as the rotation period increases in solar-type stars. The frequency of superflares decreases as the stellar rotation period increases. The maximum energy we found on Sun-like stars (P_rot&gt;20 day) is 4×10^34 erg.', 'One of the important conclusion from all Kepler data:\n\nOur analysis of Sun-like stars suggest that the Sun can cause superflares with energies of ∼7×10^33 erg (∼X700-class flares) and ∼1×10^34 erg (∼X1000-class flares) once every ∼3,000 years and ∼6,000 years, respectively.', '[Figure] Comparison between the frequency distribution of superflares on Sun-like stars and solar flares. https://t.co/y9Ockacyfb']",20,11,1733
