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…
Opacity calculations for stellar astrophysics
Jean-Christophe Pain, Franck Gilleron
Opacity is a key ingredient of stellar structure and evolution. In the present work, we recall the role of opacity in asteroseismology, focusing mainly on two kinds of astrophysica…
Detailed Opacity Calculations for Stellar Models
Jean-Christophe Pain, Franck Gilleron, Maxime Comet
Radiative opacity is an important quantity in the modeling of stellar structure and evolution. In the present work we recall the role of opacity in the interpretation of pulsations…
Detailed opacity calculations for astrophysical applications
Jean-Christophe Pain, Franck Gilleron, Maxime Comet
Nowadays, several opacity codes are able to provide data for stellar structure models, but the computed opacities may show significant differences. In this work, we present state-o…
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…
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…
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…
