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…
An Expanded Set of Los Alamos OPLIB Tables in MESA: Type-1 Rosseland-mean Opacities and Solar Models
Ebraheem Farag, Christopher J. Fontes, F. X. Timmes +11
We present a set of 1194 Type-1 Rosseland-mean opacity tables for four different metallicity mixtures. These new Los Alamos OPLIB atomic radiative opacity tables are an order of ma…
Real-Space Green's functions for Warm Dense Matter
M. Laraia, C. Hanson, N. R. Shaffer +3
Accurate modeling of the electronic structure of warm dense matter is a challenging problem whose solution would allow a better understanding of material properties like equation o…
Inversions of the Ledoux discriminant: a closer look at the tachocline
Gaël Buldgen, S. J. A. J. Salmon, M. Godart +10
Modelling the base of the solar convective envelope is a tedious problem. Since the first rotation inversions, solar modellers are confronted with the fact that a region of very li…
Seismic inversion of the solar entropy: A case for improving the Standard Solar Model
G. Buldgen, S. J. A. J. Salmon, A. Noels +9
The Sun is the most constrained and well-studied of all stars. As a consequence, the physical ingredients entering solar models are used as a reference to study all other stars obs…
Interpretation of the BRITE oscillation data of the hybrid pulsator Eridani: a call for the modification of stellar opacities
J. Daszynska-Daszkiewicz, A. A. Pamyatnykh, P. Walczak +3
The analysis of the BRITE oscillation spectrum of the main sequence early B-type star Eridani is presented. Only models with the modified mean opacity profile can account for t…
Modeling the Spectra of Dense Hydrogen Plasmas: Beyond Occupation Probability
T. A. Gomez, M. H. Montgomery, T. Nagayama +2
Accurately measuring the masses of white dwarf stars is crucial in many astrophysical contexts (e.g., asteroseismology and cosmochronology). These masses are most commonly determin…
A New Generation of Los Alamos Opacity Tables
J. Colgan, D. P. Kilcrease, N. H. Magee +6
We present a new, publicly available, set of Los Alamos OPLIB opacity tables for the elements hydrogen through zinc. Our tables are computed using the Los Alamos ATOMIC opacity and…
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…
