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).…
Modeling Flare Continuum Emission Observed by Hinode/EIS: Instrument Calibration and Element Composition Results
Peter R. Young, Biswajit Mondal
Continuum emission from a solar flare observed with the Extreme ultraviolet Imaging Spectrometer (EIS) on board the Hinode satellite is used to obtain the radiometric calibration o…
Flare-Driven Plasma Dynamics and Elemental Abundance Redistribution
Biswajit Mondal, Amy R. Winebarger
Since the advent of X-ray and EUV spectroscopy, the discovery of the First Ionization Potential (FIP) effect--where coronal elemental compositions diverge from their photospheric v…
Abundance Diagnostics from Slitless Imaging Spectrometer: A Proof-of-Concept for MaGIXS-2
Biswajit Mondal, Amy R. Winebarger, P. S. Athiray
Elemental abundance diagnostics in the solar corona are crucial for understanding energy transport, plasma heating, and magnetic activity. Most earlier imaging-spectroscopic studie…
Spatial and Temporal Distribution of Nanoflare Heating During Active Region Evolution
Biswajit Mondal, James A Klimchuk, Amy R. Winebarger +2
Nanoflares are believed to be key contributors to heating solar non-flaring active regions, though their individual detection remains challenging. This study uses a data-driven fie…
