METRIC TYPE-III BURSTS ASSOCIATED WITH SOFT-X-RAY JETS

From soft X-ray and metric radio observations with high temporal and s patial resolution, we show that electron acceleration in the form of T ype III bursts occurs in association with coronal jets observed by the Yohkoh soft X-ray telescope. The excellent correspondence between the positions of the radio sources observed at different frequencies and the X-ray jets strongly suggests that electron beams propagate along t he relatively dense paths formed by the jets. Assuming a constant temp erature for the jets, one can estimate the electron density from the s oft X-ray measurements. These computed electron densities agree well w ith the values derived from Type III bursts produced by the plasma emi ssion process. The observations are consistent with the idea that stro ng particle acceleration accompanies magnetic reconnection in these ev ents as well as in solar flares.
