GENERATION OF LARGE SCALE ELECTRIC FIELDS IN CORONAL FLARE CIRCUITS, H. Onel and G.J. Mann
Astrophysical Institute Potsdam
This paper presents the electric circuit theory championed by Hannes Alfven.A large number of energetic electrons are generated during solar flares. They carry a substantial part of the flare released energy but how these electrons are created is not fully understood yet. This paper suggests that plasma motion in an active region in the photosphere is the source of large electric currents. These currents can be described by macroscopic circuits. Under special circumstances currents can establish in the corona along magnetic field lines. The energy released by these currents when moderate assumptions for the local conditions are made, is found be comparable to the flare energy.

http://arxiv.org/PS_cache/arxiv/pdf/090 ... 0813v1.pdfCurrently several different electron acceleration mechanisms in the solar corona are known. All of these mechanisms have the principle of acceleration due to electric fields in common, but differ in the processes leading to the generation of the electric field. In the present paper the generation of a large scale DC electric field is discussed in terms of electric circuits, which is related to a current generated due to photopheric plasma motion (e.g., Alfven and Carlqvist, 1967; Sen and White, 1972; Martres et al., 1973; Heyvarts, 1974; Obayashi, 1975; Akasofu, 1979; Kan et al., 1983; Melrose, 1997; Zaitsev et al., 1998; Yang et al., 2004; Zaitsev, 2005). Motivated by these papers, the electric currents are investigated in order to obtain a mechanism for acceleration of electrons to high energies. The basic idea of this mechanism is to generate the flare energy by photopheric plasma motion in active regions. This is in contradiction to the reconnection model in which the magnetic field energy in the corona is taken for the flare.
Nereid, what is "'misleading' (at best)" in the above, circuit theory, peer-reviewed published paper?
Nereid, do you have an objection to the description and the formal mathematical equations H. Onel and G.J. Mann provided in their paper?Nereide wrote:...then it would be a VERY GOOD IDEA to take some time to describe, carefully, just what you mean.
