Abstract

We review a recently completed set of Los Alamos OPLIB opacity tables for the elements hydrogen through zinc. Our tables have been computed using the Los Alamos ATOMIC code, which makes use of atomic structure calculations that include fine-structure detail for all the elements considered. We utilize an equation-of-state model, known as ChemEOS, that is based on the minimization of free energy in a chemical picture. Recent publications by us have compared our calculations to available experimental opacity data and to other opacity calculations. Our tables are publicly available via our website, and have already been used in solar modeling calculations as well as the modeling of pulsating B-type stars. This proceedings submission will give an overview of our opacity calculations and briefly review the conclusions from the astrophysical modeling.
