A variational atomic model of plasma accounting for ion radial correlations and electronic structure of ions (VAMPIRES)
T. Blenski, R. Piron
We propose a model of ion-electron plasma (or nucleus-electron plasma) that accounts for the electronic structure around nuclei (i.e. ion structure) as well as for ion-ion correlat…
Variational average-atom model of electron-ion plasma with correlations and quantum bound electrons
R. Piron, T. Blenski
In the present paper, we propose a variational average-atom model of electron-ion plasma performing a quantum treatment of bound electrons and accounting for correlations (VAAQBEC)…
Addendum to "Free-energy functional of the Debye-Hückel model of simple fluids"
R. Piron, T. Blenski
In previous publications [arXiv:1608.08430, arXiv:1704.06502], the authors have proposed Debye-Hückel-approximate free-energy functionals of the pair distribution functions for one…
Free-energy functional of the Debye-Hückel model of two-component plasmas
T. Blenski, R. Piron
We present a generalization of the Debye-Hückel free-energy-density functional of simple fluids to the case of two-component systems with arbitrary interaction potentials. It allow…
Free-energy functional of the Debye-Hückel model of simple fluids
R. Piron, T. Blenski
The Debye-Hückel approximation to the free-energy of a simple fluid is written as a functional of the pair correlation function. This functional can be seen as the Debye-Hückel equ…
Detailed computation of hot-plasma atomic spectra
Jean-Christophe Pain, Franck Gilleron, Thomas Blenski
We present recent evolutions of the detailed opacity code SCO-RCG which combines statistical modelings of levels and lines with fine-structure calculations. The code now includes t…
The Hybrid Detailed / Statistical Opacity Code SCO-RCG: New Developments and Applications
Jean-Christophe Pain, Franck Gilleron, Quentin Porcherot +1
We present the hybrid opacity code SCO-RCG which combines statistical approaches with fine-structure calculations. Radial integrals needed for the computation of detailed transitio…
The hybrid opacity code SCO-RCG: recent developments
Jean-Christophe Pain, Franck Gilleron, Quentin Porcherot +1
Absorption and emission spectra of multicharged-ion plasmas contain a huge number of electron configurations and electric-dipolar lines, which can be handled by global methods. How…
Comparison of Fe and Ni opacity calculations for a better understanding of pulsating stellar envelopes
D. Gilles, S. Turck-Chièze, G. Loisel +19
Opacity is an important ingredient of the evolution of stars. The calculation of opacity coefficients is complicated by the fact that the plasma contains partially ionized heavy io…
Iron and Nickel spectral opacity calculations in conditions relevant for pulsating stellar envelopes and experiments
D. Gilles, S. Turck-Chièze, M. Busquet +18
Seismology of stars is strongly developing. To address this question we have formed an international collaboration OPAC to perform specific experimental measurements, compare opaci…
A consistent approach for mixed detailed and statistical calculation of opacities in hot plasmas
Quentin Porcherot, Jean-Christophe Pain, Franck Gilleron +1
Absorption and emission spectra of plasmas with multicharged-ions contain transition arrays with a huge number of coalescent electric-dipole (E1) lines, which are well suited for t…
Theoretical and experimental activities on opacities for a good interpretation of seismic stellar probes
S Turck-Chièze, G Loisel, D Gilles +23
Opacity calculations are basic ingredients of stellar modelling. They play a crucial role in the interpretation of acoustic modes detected by SoHO, COROT and KEPLER. In this review…
Radiative properties of stellar plasmas and open challenges
S. Turck-Chièze, G. Loisel, D. Gilles +24
The lifetime of solar-like stars, the envelope structure of more massive stars, and stellar acoustic frequencies largely depend on the radiative properties of the stellar plasma. U…
Thermodynamic coherence of the Variational Average-Atom in Quantum Plasmas (VAAQP) approach
R. Piron, T. Blenski, B. Cichocki
A new code called VAAQP (Variational Average-Atom in Quantum Plasmas) is reported. The model as well as main results of previous studies are briefly recalled. The code is based on…
Measurement of XUV-absorption spectra of ZnS radiatively heated foils
Nikolaos Kontogiannopoulmos, Serena Bastiani-Ceccotti, Frédéric Thais +7
Time-resolved absorption of zinc sulfide (ZnS) and aluminum in the XUV-range has been measured. Thin foils in conditions close to local thermodynamic equilibrium were heated by rad…
