For the theoretical study of X and extreme-UV spectra of ions in plasmas, quantum
mechanics brings more detailed results than statistical physics. However, it is impossible to …

Similarity solutions to the nonlinear non-equilibrium Marshak wave problem with a time
dependent radiation driving source are presented. The radiation transfer model used is the …

High-velocity stellar collisions near supermassive black holes may result in a complete
disruption of the stars. The initial disruption can have energies on par with supernovae and …

One of the challenges in calculating the opacity of dense plasmas is the difficulty in
consistently modeling electrons bound to nuclei and those that exist within the continuum of …

In hot plasmas, such as the ones encountered in astrophysics or laser-fusion studies, the
number of ionic excited states may become huge, and the relevant electron configurations …

In this article, we propose several ideas and tools in order to check the reliability of radiative
opacity and atomic physics databases. We first emphasize that it can be useful to verify that …

Calculating opacities for a wide range of plasma conditions (ie temperature, density,
element) requires detailed knowledge of the plasma configuration space and electronic …

We derive a family of similarity solutions to the nonlinear non-equilibrium Marshak wave
problem for an inhomogeneous planar medium, which is coupled to a time dependent …

Partition functions of a canonical ensemble of non-interacting bound electrons are a key
ingredient of the super-transition-array approach to the computation of radiative opacity. A …

Abstract 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 …
