Radio, X-ray, and EUV signatures of internal and external reconnection of an erupting flux rope

Jana Kašparová, Jaroslav Dudík, 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.…

Spatiotemporal evolution of UV pulsations and their connection to 3D magnetic reconnection and particle acceleration

Stefan Purkhart, Hannah Collier, Laura A. Hayes +3

Quasi-periodic pulsations (QPPs) are a common feature of impulsive solar flare emissions, yet their driving mechanism(s) remain unresolved. We study long-period (3.4 min) QPPs in t…

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…

New insights into the proton precipitation sites in solar flares

Andrea Francesco Battaglia, Säm Krucker

The Reuven Ramaty High Energy Solar Spectrocopy Imager (RHESSI) -ray observations of the extraordinary GOES X25 flare SOL2003-10-28T11:10 are revisited to investigate previously…
