Responses of the X-ray spectrometer/imager STIX onboard Solar Orbiter
Hualin Xiao, Olivier Limousin, Ewan Dickson +1
Solar flares are explosive events that release X-rays from hot plasma and accelerated electrons. The STIX instrument on the Solar Orbiter provides imaging spectroscopy of solar X-r…
Small-Scale and Transient EUV Kernels in Solar Flare Ribbons
Hannah Collier, Säm Krucker, Laura A. Hayes +3
Flare ribbons form when energy released by coronal magnetic reconnection is deposited in the low solar atmosphere, so by studying the dynamics of flare ribbons, one obtains an indi…
A magnetic avalanche as the central engine powering a solar flare
L. P. Chitta, D. I. Pontin, E. R. Priest +17
Solar flares are the most powerful, magnetically driven, explosions in the heliosphere. The nature of magnetic energy release in the solar corona that heats the plasma and accelera…
Radio, X-ray, and EUV signatures of internal and external reconnection of an erupting flux rope
Jana KaÅ¡parová, Jaroslav DudÃk, Marian Karlický +5
We analyse imaging (EUV, X-ray) and spectral (radio, X-ray) data obtained by ground based and space instruments on board space missions both on Earth (Fermi, Hinode, Solar Dynamics…
Spectral component imaging of solar X-ray flares
Muriel Zoë Stiefel, Paolo Massa, Alessia Guidetti +2
Solar hard X-ray observations provide diagnostics of the hottest plasmas and of nonthermal electron populations present during solar flares and coronal mass ejections. HXR images o…
Superhot (> 30 MK) flare observations with STIX: Joint spectral fitting
Muriel Zoë Stiefel, Natália Bajnoková, Säm Krucker
Spectroscopic analysis of large flares (>X1) in the hard X-ray (HXR) range offers unique insights into the hottest (> 30 MK) flare plasma, the so-called superhot thermal component.…
