On the computation of moments in the Super-Transition-Arrays model for radiative opacity calculations

In the Super-Transition-Array statistical method for the computation of radiative opacity of hot dense matter, the moments of the absorption or emission features involve partition functions with reduced degeneracies, occurring through the calculation of ...

Hybrid calculation of hot plasma radiative properties at local thermodynamic equilibrium involving energy levels, configurations and superconfigurations.

, 2012
In hot dense plasmas, most energy transfer is due to radiation. Therefore, the effects of opacity on structure and evolution of plasmas are quite important. Normally, detailed line by line calculation of plasma opacities give the most precise results, but sometimes requires such an amount of resources it is not tractable.

Superconfiguration widths and their effects on atomic models

High Energy Density Physics, 2010
Abstract Superconfigurations are an important component of many of the collisional-radiative atomic models that are used to predict the properties of atoms and ions in non-local thermodynamic equilibrium (non-LTE) plasmas. In this paper, we investigate the statistical properties of superconfigurations and derive expressions for their approximate ...
