A Model for U-Shaped Solar Burst Spectra. II.
Abstract
Developments of the theoretical model of Kalman and Yukon of U-shaped solar burst spectra are discussed. The basic features of the model consisting of assigning both the low- and high-frequency positions of the radiation spectrum to the same group of mildly relativistic electrons, are reviewed. The main features of the single particle source spectrum are in qualitative agreement with those of observed spectra. Integration over the pitch-angle distribution of particles improves the qualitative agreement. The radiation emitted in the dense source regionis guided by a magnetic loop into the less dense coronal regions, where it is converted by incoherent scattering on thermal dressed ions into free space electromagnetic radiation. Certain correlations suggested by the model have already been verified; others are proposed for eventual study. (Author)
