Determination of magnetic fields in generation regions of solar microwave bursts
Abstract
The paper examines limitations on the application of homogeneous models of nonthermal flare emission which affect the reliable determination of such important physical parameters as magnetic field strength and the density of fast electrons in the flare region. Consideration is given to the example of the radio burst associated with the X-ray flare of March 23, 1980, and it is shown that simultaneous high-angular-resolution (l-arcsec) observations in wide X-ray (1-1000 keV) and radio emission (1-20 GHz) ranges are necessary to construct an unambiguous model. In the absence of such information, the range of scatter of model parameters can amount to two orders of magnitude.
