Flare Physics in Solar Activity Maximum 22: Proceedings of the International SOLAR-A Science Meeting Held at Tokyo, Japan, 23–26 October 1990

Y. Uchida (auth.), Yutaka Uchida, Richard C. Canfield, Tetsuya Watanabe, Eijiro Hiei (eds.)354054383X, 9783540543831, 038754383X

The book reviews the knowledge obtained from ground-based and space-borne solar flare research thus at the same time preparing for the forthcoming mission of the satellite Solar A which will be launched in 1991. Accordinglyone section is devoted to experiments on Solar A. The rest review both theory and observational facts to give a physically realistic picture of flares, including problems of magnetic flux emergence, high energy particles in flares, heating and flows in flares, and further problems of solar activity.
