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…
Defining the Middle Corona
Matthew J. West, Daniel B. Seaton, David B. Wexler +31
The middle corona, the region roughly spanning heliocentric altitudes from to , encompasses almost all of the influential physical transitions and processes that…
Future perspectives in solar hot plasma observations in the soft X-rays
Alain Jody Corso, Giulio Del Zanna, Vanessa Polito
The soft X-rays (SXRs: 90--150 ) are among the most interesting spectral ranges to be investigated in the next generation of solar missions due to their unique capability of dia…
Large-scale multiconfiguration Dirac-Hartree-Fock calculations for astrophysics: n=4 levels in P-like ions from Mn~XI to Ni~XIV
C. X. Song, K. Wang, G. Del Zanna +9
Using the multiconfiguration Dirac-Hartree-Fock and the relativistic configuration interaction methods, a consistent set of transition energies and radiative transition data for th…
R-matrix electron-impact excitation data for the C-like iso-electronic sequence
Junjie Mao, N. R. Badnell, G. Del Zanna
Emission and absorption features from C-like ions serve as temperature and density diagnostics of astrophysical plasmas. -matrix electron-impact excitation data sets for C-like…
CHIANTI - an atomic database for emission lines - Paper XV: Version 9, improvements for the X-ray satellite lines
Kenneth P. Dere, Giulio Del Zanna, Peter R. Young +2
CHIANTI contains a large quantity of atomic data for the analysis of astrophysical spectra. Programs are available in IDL and Python to perform calculation of the expected emergent…
Modelling ion populations in astrophysical plasmas: carbon in the solar transition region
R. P. Dufresne, G. Del Zanna
The aim of this work is to improve the modelling of ion populations in higher density, lower temperature astrophysical plasmas, of the type commonly found in lower solar and stella…
Incorporating Uncertainties in Atomic Data Into the Analysis of Solar and Stellar Observations: A Case Study in Fe XIII
Xixi Yu, Giulio Del Zanna, David C. Stenning +6
Information about the physical properties of astrophysical objects cannot be measured directly but is inferred by interpreting spectroscopic observations in the context of atomic p…
