The Opacity Project: R-Matrix Calculations for Opacities of High-Energy-Density Astrophysical and Laboratory Plasmas
Anil K. Pradhan, Sultana N. Nahar
Accurate determination of opacity is critical for understanding radiation transport in both astrophysical and laboratory plasmas. We employ atomic data from R-Matrix calculations t…

Helioseismic inference of the solar radiative opacity
Gaël Buldgen, Jean-Christophe Pain, Philippe Cossé +18
The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current deb…
