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…

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…
