A new concept for solar flares
Abstract
Solar flare theories fail on two counts to model the observations; both the total power and the number of particles required to explain the emissions cannot be supplied by the active region. We invoke here a global view, where an erupting magnetic structure plays the central role and the active region plays a minor role. Magnetic reconnection in the high corona gradually "pumps up" the erupting structure with mildly energetic particles, mainly protons. Finally the stability of the structure is destroyed, and it erupts, dumping the particles into the evolving active region, where they are reaccelerated to produce the high energy flare protons, and other emissions. The energy and matter supplied by the erupting structure is sufficient to overcome the active region deficit.
