Thermal runaway as the solar flare trigger mechanism

Abstract

It is postulated that the solar flare ‘trigger’ mechanism is a thermal runaway which occurs in the inner corona. This runaway is the result of a radiative power function which decreases with increasing temperature. Relationships of the onsets of Hα flares, hard X-ray, soft X-ray and centimeter radio bursts are consistent with the model. Flares are shown to be common solar phenomena which occur preferentially in hot and dense active regions.
