Evidence of Extreme Ultraviolet Resonant Excitation in the Middle Corona During A Solar Flare

Daniel B. Seaton, Cooper Downs, Giulio Del Zanna +10

We present observations of an eruptive solar flare on 2016 January 6 that occurred behind the solar limb from the perspective of the Earth, but was well observed by STEREO and the…

Modelling Stellar Irradiances II: Correlations of solar irradiances with proxies of activity along a cycle

E. Deliporanidou, G. Del Zanna, T. N. Woods +1

There is a pressing need to model X-ray Ultra-Violet (XUV: 1-30 nm) stellar irradiances, given the scarcity of current measurements. One of the measurable effects of a stellar cycl…

CHIANTI -- an atomic database for emission lines -- Paper XVIII. Version 11, advanced ionization equilibrium models: density and charge transfer effects

R. P. Dufresne, G. Del Zanna, P. R. Young +4

Version 11 of the CHIANTI database and software package is presented. Advanced ionization equilibrium models have been added for low charge states of seven elements (C, N, O, Ne, M…

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…

Multi-wavelength observations of a B-class flare using XSM, AIA, and XRT

Yamini K. Rao, B. Mondal, Giulio Del Zanna +5

We present multi-wavelength observations by Chandrayaan-2/XSM, SDO/AIA and Hinode/XRT of a B-class flare observed on 25th February, 2021, originating from an active region (AR 1280…

New atomic data for C I Rydberg states compared with solar UV spectra

P. J. Storey, R. P. Dufresne, G. Del Zanna

We use the Breit Pauli -matrix method to calculate accurate energies and radiative data for states in C I up to =30 and with . We provide the full dataset of decays t…
