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…

Constraining turbulent solar flare acceleration regions by connecting kinetic modeling and X-ray observations

Morgan Stores, Natasha Jeffrey, Ewan Dickson +2

Spatially-resolved X-ray observations are the key to understanding electron acceleration in solar flares. Currently, the underlying processes that efficiently energize solar flare…

Using the STIX background detector as a proxy for GOES

Muriel Zoë Stiefel, Matej Kuhar, Olivier Limousin +4

Context. The Spectrometer/Telescope for Imaging X-Rays (STIX) onboard Solar Orbiter was designed to observe solar flares in the X-ray range of 4-150 keV, providing spectral, tempor…

A machine learning approach for computing solar flare locations in X-rays on-board Solar Orbiter/STIX

Paolo Massa, Simon Felix, László István Etesi +7

The Spectrometer/Telescope for Imaging X-rays (STIX) on-board the ESA Solar Orbiter mission retrieves the coordinates of solar flare locations by means of a specific sub-collimator…

Multipoint study of the rapid filament evolution during a confined C2 flare on 28 March 2022, leading to eruption

Stefan Purkhart, Astrid M. Veronig, Bernhard Kliem +5

We studied the rapid filament evolution in AR 12975 during a confined C2 flare on 28 March 2022, which led to an eruptive M4 flare 1.5 h later. It is characterized by the breakup o…

Efficiency of solar microflares in accelerating electrons when rooted in a sunspot

Jonas Saqri, Astrid M. Veronig, Andrea Francesco Battaglia +3

We investigate two microflares of GOES classes A9 and C1 (after background subtraction) observed by STIX onboard Solar Orbiter with exceptionally strong nonthermal emission. We com…
