TL;DR: Measurements of iron-plasma transmission at 156+/-6 eV electron temperature and 6.9+/-1.7 x 10(21) cm(-3) electron density are reported, permitting the first direct experimental tests of absorption features critical for understanding solar interior radiation transport.

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: 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: The 5th non-LTE kinetics code comparison workshop was held in November 2007 as discussed by the authors, where steady-state and time-dependent cases for elements ranging from carbon to gold were examined in detail.

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.
