FLARE-ASSOCIATED TYPE III RADIO BURSTS AND DYNAMICS OF THE EUV JET FROM SDO/AIA AND RHESSI OBSERVATIONS

摘要

We present a detailed description of the interrelation between the Type?III radio bursts and energetic phenomena associated with the flare activities in active region AR11158 at 07:58?UT on 2011 February?15. The timing of the Type?III radio burst measured by the radio wave experiment on Wind/WAVE and an array of ground-based radio telescopes coincided with an extreme-ultraviolet (EUV) jet and hard X-ray (HXR) emission observed by SDO/AIA and RHESSI, respectively. There is clear evidence that the EUV jet shares the same source region as the HXR emission. The temperature of the jet, as determined by multiwavelength measurements by Atmospheric Imaging Assembly, suggests that Type?III emission is associated with hot, 7?MK, plasma at the jet's footpoint.
