Abstract
In 2015 Los Alamos National Laboratory (LANL) released a new set of OPLIB opacity tables for the elements hydrogen through zinc. The new LANL opacities are publicly available via our website and are already in use by the astrophysics community. In this contribution, we discuss the extension of our opacity calculations to elements beyond zinc. Such calculations are motivated by potential industrial applications (for elements such as Sn) as well as available experimental data with which to compare our calculations (for Ge and Br). After a short outline of our method for computing opacities for these elements, we make comparisons to available experimental data and find good agreement. Future plans are briefly discussed.
Highlights
The importance of accurate and comprehensive sets of opacities to astrophysics can hardly be overstated
After completion of the opacity tables for H through Zn, we considered the feasibility of extending our tables beyond zinc
This was motivated by recent inertial confinement fusion (ICF) measurements that use Kr (Z = 36) as a dopant in implosion measurements at the National Ignition Facility (NIF) [12]
Summary
The importance of accurate and comprehensive sets of opacities to astrophysics can hardly be overstated. Los Alamos opacities have been used for many years in stellar modeling [1,2,3] and the recent release of new OPLIB tables [4] provides the latest comprehensive set of tables for hydrogen through zinc. Several short summaries of our new opacity tables for hydrogen through zinc have recently been published in various proceedings [10,11], and instead of repeating such summaries, we aim instead in this contribution to provide a short description of some recent work by us that attempts to calculate opacities for elements beyond zinc Such extensions are motivated by the continuing importance of accurate opacities and radiation transport models to other plasma studies found in inertial confinement fusion (ICF) research (e.g., [12,13,14]), industrial plasmas [15], and in the field of magnetic confinement fusion.
