Flare-associated type III radio bursts and dynamics of the EUV jet from SDO/AIA and RHESSI observations

TL;DR

This paper investigates the relationship between Type III radio bursts, EUV jets, and hard X-ray emissions in solar active region AR 11158, revealing that they originate from the same source region and involve hot plasma at the jet's footpoint.

Contribution

It provides a detailed multiwavelength analysis linking radio bursts with EUV and X-ray phenomena, highlighting the hot plasma's role in jet-associated radio emissions.

Findings

Type III bursts coincide with EUV jets and X-ray emissions.

EUV jet shares the same source region as hard X-ray emission.

Jet plasma temperature is approximately 7 MK.

Abstract

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 AR 11158 at 07:58 UT on 2011, Feb. 15. The timing of the Type-III radio burst measured by the radio wave experiment on the Wind/WAVE and an array of ground-based radio telescopes, coincided with an EUV jet and hard X-ray emission observed by SDO/AIA and RHESSI., respectively. There is clear evidence that the EUV jet shares the same source region as the hard X-ray emission. The temperature of the jet, as determined by multiwavelength measurements of AIA, suggests that type III emission is associated with hot, 7 MK, plasma at the jet's footpoint.
