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…

A 3D Model of AR 11726 Heated by Nanoflares

Joel Allred, Adrian Daw, Jeffrey Brosius

The Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS) and the Hinode/ EUV Imaging Spectrometer (EIS) observed AR 11726 on 2013 April 23. We present intensity images in nume…

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…

Emission lines of Fe XI in the 257--407 A wavelength region observed in solar spectra from EIS/Hinode and SERTS

F. P. Keenan, R. O. Milligan, D. B. Jess +5

Theoretical emission-line ratios involving Fe XI transitions in the 257-407 A wavelength range are derived using fully relativistic calculations of radiative rates and electron imp…
