We present the first observational tests of existing theories for the generation of type III radio bursts emitting at the fundamental plasma frequency, ωpe. This study is based on local radio emission and in situ wave phenomena associated with four interplanetary type III radio bursts observed by the unified radio and plasma wave experi…

Implications of the Soft X-Ray versus Hard X-Ray Temporal Relationship in Solar Flares

We have calculated the time profiles of spatially integrated hard X-ray (30-500 keV) and soft X-ray (1-8 Å) emission in both thick-target electron-heated models, and bulk heated thermal models, of the impulsive phase of solar flares. For the thermal model, we find a serious difficulty: the time profiles of the 30-500 keV hard X-ray emission do not…
