Solar UV and X-ray spectral diagnostics
Giulio Del Zanna,Helen E. Mason +1 more
TL;DR: In this article, a review of the diagnostic methods used to measure electron densities, electron temperatures, differential emission measure (DEM), and relative chemical abundances is presented, focusing on the optically thin emission from the solar atmosphere, mostly found at UV and X-ray (XUV) wavelengths.

Soft X-ray images of the solar corona with a normal-incidence Cassegrain multilayer telescope.
TL;DR: High-resolution images of the sun in the soft x-ray to extreme ultraviolet(EUV) regime have been obtained with normal-incidence Cassegrain multilayer telescopes operated from a sounding rocket in space, allowing distinct groups of emission lines to be isolated in the solar corona and the transition region.

Spectroscopic diagnostics in the VUV for solar and stellar plasmas
Abstract: The VUV emission spectra from the solar atmosphere and stellar atmospheres have been intensively studied during the past 25 years with several major space programs In this review we discuss the spectroscopic diagnostic techniques used to study astrophysical plasmas, the atomic processes involved, the recent observations and the plans for future space missions

Theoretical investigation of spectra of multicharged ions of F-like and Ne-like isoelectronic sequences
TL;DR: In this article, Relativistic perturbation theory with the zeroth approximation of the model was used to calculate energy levels for the configurations 1s22s22p5 3s, 3p, 3d, 1s 22s2p6 3s and 3p 3d in Ne-like ions.
