Stellar superflare Archives

Spatial localization of the example superflare. (A) Kepler image of the same flare on KIC 8183083 as in Fig. 1 during the maximum flare light. (B) The same flare 30 min later. Greyscale (see color bar) indicates the flux in each pixel during the flare. The blue outlines indicate the four pixels used to extract the light curve (Fig. 1) and the cyan star is the catalog position of the star (25). The orange ellipses indicate the 68%, 95%, and 99.9% confidence levels obtained by fitting a model of a point source to those images. The star is located within the 99.9% confidence contour in both images, so we attribute the flare in the light curve to this target. -- astro-ph.SR

Stellar superflares are energetic outbursts of electromagnetic radiation, similar to solar flares but releasing more energy, up to 1036 erg on main sequence stars.
