A New Framework for Modeling Solar Flares from MHD to Kinetic Processes
Joel C. Allred, Graham S. Kerr, Silvina E. Guidoni +4
Physical processes in solar flares span many orders of magnitude in spatiotemporal scales, so a single unified model accounting for all relevant processes remains computationally i…
Flare Impulsive-phase Durations
Brian R. Dennis, Hugh Hudson, Joel Allred
This Research Note is in response to the recent paper by S. M. Perriyil et al. (2026). They provide measurements of the time delay (delta t) between the hard X-ray and soft X-ray p…
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…
Fe I 6173 Å Emission During White-Light Solar Flares
Samuel Granovsky, Alexander G. Kosovichev, Viacheslav M. Sadykov +2
Between 2017 and 2024, the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory has observed numerous white-light solar flares (WLFs). HMI spectro-polarime…
Solar Flare Ribbon Fronts. II. Evolution of heating rates in individual flare footpoints
Graham S. Kerr, Vanessa Polito, Yan Xu +1
Solar flare ribbon fronts appear ahead of the bright structures that normally characterise solar flares, and can persist for an extended period of time in spatially localised patch…
An Optically Thin View of the Flaring Chromosphere: Nonthermal widths in a chromospheric condensation during an X-class solar flare
Graham S. Kerr, Adam F. Kowalski, Joel C. Allred +2
The bulk of solar flare energy is deposited in the chromosphere. Flare ribbons and footpoints in the chromosphere therefore offer great diagnostic potential of flare energy release…
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…
COMPLETE: A flagship mission for complete understanding of 3D coronal magnetic energy release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
COMPLETE is a flagship mission concept combining broadband spectroscopic imaging and comprehensive magnetography from multiple viewpoints around the Sun to enable tomographic recon…
Investigating the response of loop plasma to nanoflare heating using RADYN simulations
V. Polito, P. Testa, J. Allred +5
We present the results of 1D hydrodynamic simulations of coronal loops which are subject to nanoflares, caused by either in-situ thermal heating, or non-thermal electrons (NTE) bea…
Forward Modeling of Synthetic EUV/SXR Emission from Solar Coronal Active Regions: Case of AR 11117
V. S. Airapetian, J. Allred
Recent progress in obtaining high spatial resolution images of the solar corona in the extreme-ultraviolet (EUV) with Hinode, TRACE, SDO and recent Hi-C missions and soft X-ray (SX…
