Cellular automaton models of solar flare occurrence, A&A 310, L9, 1996


Abstract

We describe a class of stochastic cellular automaton models for the occurrence of solar flares. "Flaring elements" of a deliberately unspecified nature are supposed to interact. A 1-D version of the model, capable of analytical description, conflicts in detail with observations but indicates the qualitative success of such a picture. Minimal a priori assumptions are involved. The qualitative importance of such a model lies in the arbitrary means of communication between flaring elements.
