Elemental Composition Evolution during the 2024 September 30 Solar Eruption: A Comparison of Hot and Cool Plasma Components with Solar Orbiter/SPICE, Hinode/EIS, and Chandrayaan-2/XSM
Momchil Molnar, Joseph Plowman, Amir Caspi +7
Solar plasma composition differs between the photosphere and corona over a range of timescales, with preferential enhancement of elements with low first ionization potential (FIP).…
Spectroscopic He I 1083 nm prominence eruption observations in the middle corona with MLSO/UCoMP
Chloe Pistelli, Momchil E Molnar, Giuliana de Toma +1
Coronal mass ejections (CMEs) are a major driver of space weather as they propagate through the heliosphere. Many CMEs have associated prominence material entangled in their magnet…
Detection of "diffuse" coronal He I 1083 during the April 8 2024 Solar Eclipse: evidence for terrestrial atmospheric scattering origin
M. E. Molnar, R. Casini, P. Bryans +2
Strong He I 1083 nm atomic line signals have been previously measured during total solar eclipses at coronal heights above the lunar limb. This rather unexpected measurement has ki…
PINN ME: A Physics-Informed Neural Network Framework for Accurate Milne-Eddington Inversions of Solar Magnetic Fields
Robert Jarolim, Momchil E. Molnar, Benoit Tremblay +2
Spectropolarimetric inversions of solar observations are fundamental for the estimation of the magnetic field in the solar atmosphere. However, instrumental noise, computational re…
