X-Ray and Radio Properties of Solar 3He-rich Events
Abstract
Radio and X-ray properties of solar flares associated with a new sample of individual (He-3) rich solar particle events are examined. Given the association between kilometric type III bursts and (He-3) rich events, the timing of the radio events is used to identify the related X-ray increases. The X-ray events exhibit a rich variety, from the standpoint of both intensity and complexity. Examination of the events shows statistically significant anticorrelations between the He-3/He-4 ratio and the intensity of the event as measured at kilometric wavelengths and in hard and soft X-rays; larger He-3/He-4 ratios occur in smaller flares. The result suggests that a coupling may exist between the preheating phase and the acceleration phase of these events or that mixing occurs between an enriched particle population accelerated within the compact flare and a normal population accelerated by a shock propagating away from an intense flare.
