First results from PADRE/MeDDEA: X-rays from a flare and its CME
Muriel Zoë Stiefel, Säm Krucker, Olivier Limousin +22
The MeDDEA hard X-ray spectrometer onboard NASAs PADRE CubeSat operates four flight-spare detectors from the Solar Orbiter/STIX instrument. This paper aims to evaluate the accuracy…
Fine-scale flare structures and their energetic implications from short-exposure extreme-ultraviolet imaging
Laura A. Hayes, Hannah Collier, Säm Krucker +5
To capture the brightest and most rapidly evolving phases of solar flares, the Major Flare Solar Orbiter Observing Plan employed a dedicated short-exposure mode for the High Resolu…
Quasi-periodic pulsations and three-dimensional magnetic reconnection during 2022 March 31 flare observed by IRIS & STIX
Juraj Lorincik, Hannah Collier, Vanessa Polito +3
Apparent slipping motions of flare ribbon kernels and the formation of hard X-ray (HXR) footpoints are important signatures of magnetic reconnection in solar flares. Ultraviolet (U…
Understanding Solar Flares and Energetic Events: Open questions, observational requirements, and instrumental needs over the coming decade
Malcolm K. Druett, Graham S. Kerr, Joel C. Allred +15
Solar flares are the largest energy-release events in the Solar System, allowing us to study fundamental physical phenomena under extreme conditions. Those include magnetic reconne…
Solar Orbiter's 2024 Major Flare Campaigns: An Overview
Daniel F. Ryan, Laura A. Hayes, Hannah Collier +17
Solar Orbiter conducted a series of flare-optimised observing campaigns in 2024 utilising the Major Flare Solar Orbiter Observing Plan (SOOP). Dedicated observations were performed…
Solar flares in the Solar Orbiter era: Short-exposure EUI/FSI observations of STIX flares
Hannah Collier, Laura A. Hayes, Stefan Purkhart +10
Aims: This paper aims to demonstrate the importance of short-exposure extreme ultraviolet (EUV) observations of solar flares in the study of particle acceleration, heating and ener…
High-Energy Insights from an Escaping Coronal Mass Ejection with Solar Orbiter/STIX Observations
Laura A. Hayes, Säm Krucker, Hannah Collier +1
Solar eruptive events, including solar flares and coronal mass ejections (CMEs), are typically characterised by energetically significant X-ray emissions from flare-accelerated ele…
Non-thermal Observations of a Flare Loop-top using IRIS Fe XXI: Implications for Turbulence and Electron Acceleration
William Ashfield, Vanessa Polito, Sijie Yu +2
The excess broadening of high-temperature spectral lines, long observed near the tops of flare arcades, is widely considered to result from magnetohydrodynamic (MHD) turbulence. Ac…
Localising pulsations in the hard X-ray and microwave emission of an X-class flare
Hannah Collier, Laura A. Hayes, Sijie Yu +5
Aims: This work aims to identify the mechanism driving pulsations in hard X-ray (HXR) and microwave emission during solar flares. Here, by using combined HXR and microwave observat…
A Modelling Investigation for Solar Flare X-ray Stereoscopy with Solar Orbiter/STIX and Earth Orbiting Missions
Natasha L. S. Jeffrey, Säm Krucker, Morgan Stores +9
The Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter (SolO) provides a unique opportunity to systematically perform stereoscopic X-ray observations of solar…
The Focusing Optics X-ray Solar Imager (FOXSI)
Steven Christe, Meriem Alaoui, Joel Allred +26
FOXSI is a direct-imaging, hard X-ray (HXR) telescope optimized for solar flare observations. It detects hot plasma and energetic electrons in and near energy release sites in the…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
