Electron acceleration, Decimetric Solar radio bursts and Solar hard X-ray bursts observed by RHESSI
Abstract
Characteristics of the acceleration and propagation of electrons in the solar corona during a solar flare are deduced from a correlated study of decimetric radio bursts and impulsive hard X-ray bursts. Decimetric type III bursts and other fine structures in the frequency range of (1000-2000) MHz have been observed with the Brazilian Solar Decimetric Spectroscope. Corresponding radio observations in the (800-4500) MHz frequency range were made with the Ondrejov radio Telescopes. High resolution sprectra and images of solar hard X-ray bursts in 3 keV - 15 MeV range obtained by the recently launched RHESSI spacecraft are compared with the radio observations to determine the temporal relationship and its dependence on the characteristics of the radio bursts and hard X ray bursts. Early results from this- correlated study of ground-based radio observations and and spacecraft -observations of solar X-ray flares will be reported.
