TL;DR: Measurements of wavelength-resolved iron opacity at electron temperatures and electron densities at the solar radiation/convection zone boundary show that wavelength-dependent opacity is 30–400 per cent higher than predicted, which represents roughly half the change in the mean opacity needed to resolve the solar discrepancy.

TL;DR: The Los Alamos suite of relativistic atomic physics codes is a robust, mature platform that has been used to model highly charged ions in a variety of ways The suite includes capabilities for calculating data related to fundamental atomic structure, as well as the processes of photoexcitation, electron-impact excitation and ionization, photoionization and autoionization within a consistent framework as discussed by the authors.

TL;DR: In this article, the authors present a new, publicly available set of Los Alamos OPLIB opacity tables for the elements hydrogen through zinc, which are computed using the ATOMIC opacity and plasma modeling code.

TL;DR: Development of ATOMIC, a Los Alamos code designed to compute opacities under both LTE and non-LTE conditions for a large range of elements, and data associated with the newly generated Rosseland opacity table for oxygen are reported on.

TL;DR: An overview of the opacity calculations of an equation-of-state model, known as ChemEOS, that is based on the minimization of free energy in a chemical picture, is given.
