Model of a solar flare with subphotospheric energy source.

Recent experimental data give evidence that subphotospheric processes are the source of energy for solar flares, and that the magnetic field of the subphospheric region plays a passive role in the transport of energy from under the photosphere into the coronal energy transport zone. A model of solar flares is proposed, in which the sun is assumed to be a completely convective star. The model makes possible a new prediction of large-scale solar flares and demonstrates the existence of a specific (dome-shaped) structure in the family of homogeneous surfaces of the magnetic field in the flaring region.
