Light curves of typical superflares.(a) Long-term light variations of the G-dwarf KIC 11610797. The vertical axis means the relative difference between the observed brightness of the star and the average brightness during the observation period. The horizontal axis means the times of the observations in Barycentric Julian Date. (b) Enlarged light curve of a superflare observed around Barycentric Julian Date (BJD) 2454981.63 (indicated by the down arrow in panel (a)). Filled squares with solid lines and dashed lines represent the light curves from short- and long-cadence data, respectively. The long-cadence light curve is shifted in vertical direction for clarity. The flare peak (t 0) is BJD 2454981.6315 and the bolometric energy of this flare (E flare) is 1.2×1035 erg. (c) Same as panel (a), but for KIC 11551430. (d) Same as panel (b), but for the superflare observed on KIC 11551430 around BJD 2456208.35 (down arrow in panel (c)). (e) Same as panel (a), but for KIC 10338279. (f) Same as panel (b), but for the superflare observed on KIC 4543412 around BJD 2455208.68 (down arrow in panel (e)). (g) Same as panel (a), but for KIC 11253827. (h) Same as panel (b), but for the superflare observed on KIC 11253827 around BJD 2456365.27 (down arrow in panel (g)).
