Spectroscopic analysis and RHD modeling of the first Ca II H and H-epsilon flare spectra from DKIST/ViSP
Cole Tamburri, Adam Kowalski, Gianna Cauzzi +7
We analyze decay phase observations of the GOES class C6.7 flare SOL2022-08-19T20:31 by the Visible Spectropolarimeter (ViSP) on the National Science Foundation's Daniel K. Inouye…
Investigating Pre-flare Signatures in Spectroscopic Observations of an X9-class Solar Flare
Louis Seyfritz, Maria Kazachenko, Ryan French
On October 3rd, 2024, the Sun emitted an X9.0-class flare from active region NOAA 13842. The event was recorded by multiple space-based instruments, beginning hours before the erup…
Spectral Irradiance Variability in Lyman-Alpha Emission During Solar Flares
Luke Majury, Ryan Milligan, Elizabeth Butler +2
The Lyman-alpha (Lyα;1216 à ) line is the brightest emission line in the quiescent solar spectrum and radiates a significant fraction of the available nonthermal energy during fla…
Investigating the Magnetic Imprints of Major Solar Eruptions with SDO/HMI High-Cadence Vector Magnetograms
Xudong Sun, J. Todd Hoeksema, Yang Liu +2
The solar active region photospheric magnetic field evolves rapidly during major eruptive events, suggesting appreciable feedback from the corona. Previous studies of these "magnet…
Challenges and Advances in Modeling of the Solar Atmosphere: A White Paper of Findings and Recommendations
Serena Criscuoli, Maria Kazachenko, Irina Kitashvili +5
The next decade will be an exciting period for solar astrophysics, as new ground- and space-based instrumentation will provide unprecedented observations of the solar atmosphere an…
Quantifying Poynting flux in the Quiet Sun Photosphere
Dennis Tilipman, Maria Kazachenko, Benoit Tremblay +3
Poynting flux is the flux of magnetic energy, which is responsible for chromospheric and coronal heating in the solar atmosphere. It is defined as a cross product of electric and m…
