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…

Next-Generation Comprehensive Data-Driven Models of Solar Eruptive Events

Joel C. Allred, Graham S. Kerr, Meriem Alaoui +11

Solar flares and coronal mass ejections are interrelated phenomena that together are known as solar eruptive events. These are the main drivers of space weather and understanding t…

The F-CHROMA grid of 1D RADYN flare models

Mats Carlsson, Lyndsay Fletcher, Joel Allred +6

Context: Solar flares are the result of the sudden release of magnetic energy in the corona. Much of this energy goes into accelerating charged particles to high velocity. These pa…

Prospects of Detecting Non-thermal Protons in Solar Flares via Lyman Line Spectroscopy: Revisiting the Orrall-Zirker Effect

Graham S. Kerr, Joel C. Allred, Adam F. Kowalski +5

Solar flares are efficient particle accelerators, with a substantial fraction of the energy released manifesting as non-thermal particles. While the role that non-thermal electrons…

Solar Ellerman Bombs in 1-D Radiative Hydrodynamics

A. Reid, M. Mathioudakis, A. Kowalski +2

Recent observations from the Interface Region Imaging Spectrograph (IRIS) appear to show impulsive brightenings in high temperature lines, which when combined with simultaneous gro…

Solving the Coronal Heating Problem using X-ray Microcalorimeters

Steven Christe, Simon Bandler, Edward DeLuca +7

Even in the absence of resolved flares, the corona is heated to several million degrees. However, despite its importance for the structure, dynamics, and evolution of the solar atm…
