The First Flight of the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
Sabrina L. Savage, Amy R. Winebarger, Ken Kobayashi +34
The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) sounding rocket experiment launched on July 30, 2021 from the White Sands Missile Range in New Mexico. MaGIXS is a unique…
The impact of multi-fluid effects in the solar chromosphere on the ponderomotive force under LTE and NEQ ionization conditions
Juan Martínez-Sykora, Bart De Pontieu, Viggo H. Hansteen +3
The ponderomotive force is suggested to be the main mechanism to produce the so-called first ionization potential (FIP) effect - the enrichment of low FIP elements observed in the…
Coronal Abundances in an Active Region: Evolution and Underlying Chromospheric and Transition Region Properties
Paola Testa, Juan Martinez-Sykora, Bart De Pontieu
The element abundances in the solar corona and solar wind are often different from those of the solar photosphere, typically with a relative enrichment of elements with low first i…
A Statistical Study of IRIS Observational Signatures of Nanoflares and Non-thermal Particles
Kyuhyoun Cho, Paola Testa, Bart De Pontieu +1
Nanoflares are regarded as one of the major mechanisms of magnetic energy release and coronal heating in the solar outer atmosphere. We conduct a statistical study on the response…
Diagnostics of non-Maxwellian electron distributions in solar active regions from Fe XII lines observed by Hinode/EIS and IRIS
G. Del Zanna, V. Polito, J. Dudík +3
We present joint Hinode/EIS and IRIS observations of Fe XII lines in active regions, both on-disk and off-limb. We use an improved calibration for the EIS data, and find that the 1…
The Solar X-ray Corona
Paola Testa, Fabio Reale
The X-ray emission from the Sun reveals a very dynamic hot atmosphere, the corona, which is characterized by a complex morphology and broad range of timescales of variability and s…
