WorkOp-IV summary: lessons from iron opacities

TLDR
The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was held in Madrid in 1997 as mentioned in this paper, with a focus on iron opacities, and the astrophysically important photon absorption region between 50 and 80 eV was emphasized for a sequence of iron plasmas at densities and temperatures that produce nearly the same average ionization stage (Z ∗ ∼8.6).
Abstract
The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was held in Madrid in 1997. Results of this workshop are summarized with a focus on iron opacities. In particular, the astrophysically important photon absorption region between 50 and 80 eV is emphasized for a sequence of iron plasmas at densities and temperatures that produce nearly the same average ionization stage (Z ∗ ∼8.6) . Experimental data that addressed this spectral region is also reviewed.

Radiative properties for astrophysical plasma mixtures in nonlocal thermodynamic equilibrium

TL;DR: In this paper, a study of the plasma radiative properties of oxygen and iron and an astrophysical plasma mixture in non-local thermodynamic steady-state equilibrium is carried out, and departures from coronal and local thermodynamic equilibria in terms of density and temperature are also analyzed.

Measurements of niobium absorption spectra in plasmas with nearly full M-shell configurations

TL;DR: In this paper, a systematic study has been carried out on the changes in the L-shell absorption structure of niobium as a result of changing the population of the n = 3 shell from full to having vacancies in the 3D level.
