A sudden fine-scale bright kernel captured by Hi-C Flare in 11 MK emission during an M1.6-class solar flare's post-maximum phase
Sanjiv K. Tiwari, Navdeep K. Panesar, Ronald L. Moore +17
On April 17, 2024, the third successful Hi-C sounding rocket flight, Hi-C Flare, recorded coronal images in Fe XXI 129 A emission from 11 MK plasma during the post-maximum phase of…
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…
Determining the magnetic field of active region plages using the whole CLASP2/2.1 spectral window
David Afonso Delgado, Tanausú del Pino Alemán, Javier Trujillo Bueno +16
The Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable for studying the ma…
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…
A systematic study of inverting overlappograms: MaGIXS -- A case study
P. S. Athiray, Arthur Hochedez, Amy R Winebarger +1
Slitless (or wide field) imaging spectroscopy provides simultaneous imaging and spectral information from a wide field of view, which allows for rapid spectroscopic data collection…
Determining the nanoflare heating frequency of an X-ray Bright Point observed by MaGIXS
Biswajit Mondal, P. S. Athiray, Amy R. Winebarger +18
Nanoflares are thought to be one of the prime candidates that can heat the solar corona to its multi-million kelvin temperature. Individual nanoflares are difficult to detect with…
