THE SOLAR FLARE PHENOMENON AND THE THEORY OF RECONNECTION AND ANNIHILATION OF MAGNETIC FIELDS

摘要: A study is presented of the observations and theory relevant to belief that solar-flare phenomenon a direct consequence annihilation magnetic fields on sun. There very little in support such views. systematic theoretical mechanisms for diffusion, reconnection, presented. The discussed are Joule dissipation, ambipolar various forms Sweet's mechanism. It shown mechanism much more effective highly compressible medium if merging exactiy antiparallel. None known sufficiently rapid account solar flare from fields. Errors omissions discussions problem cited. Since no possible energy source other than known, question field remains both open pressing. possibilities runaway electrons hydrodynamic instability, as means hastening magnetic-field annihilation, considered. there reason expect instability unless exactly (auth)
