Microwave and hard X-ray emission bursts during solar flares.
Abstract
Analysis of time intervals and peak fluxes between hard X-rays (HXRs) of energies 17-40 keV and solar microwave (MW) bursts observed at 3.75, 9.4, and 17 GHz during impulsive and extended solar flares shows both simultaneous emission between MW and HXR emissions and delay at onset and peak. The flares showing simultaneous emission between MW and HXR emissions may be simple loop flares. The time delay may be due to the differences in source location, mechanism, and kinetic energies of electrons required to produce MW and HXR emission bursts. The peak fluxes of the MW and the HXR emissions are well correlated during impulsive flares. Radio flux and photon counts/s increase linearly, suggesting that they may be produced by the same species of accelerated solar particles.
