A new generation of los alamos opacity tables
James Colgan,David P. Kilcrease,N. H. Magee,M. E. Sherrill,Joe Abdallah,Peter Hakel,Christopher J. Fontes,Joyce A. Guzik,Katie Mussack +8 more
TL;DR: In this article, the authors present a new, publicly available set of Los Alamos OPLIB opacity tables for the elements hydrogen through zinc, which are computed using the ATOMIC opacity and plasma modeling code.

A New Generation of Los Alamos Opacity Tables
James Colgan,David P. Kilcrease,N. H. Magee,M. E. Sherrill,Joe Abdallah,Peter Hakel,Christopher J. Fontes,Joyce A. Guzik,Katie Mussack +8 more
TL;DR: This paper presents a new, publicly available set of Los Alamos OPLIB opacity tables for the elements hydrogen through zinc, and discusses in detail the calculations that are performed, and presents some comparisons of the monochromatic opacities with measurements and other opacity codes.

Massive pulsating stars observed by BRITE-Constellation - I. The triple system β Centauri (Agena)
Andrzej Pigulski,Henryk Cugier,Adam Popowicz,Rainer Kuschnig,A. F. J. Moffat,Slavek M. Rucinski,A. Schwarzenberg-Czerny,Werner W. Weiss,Gerald Handler,Gregg A. Wade,Otto Koudelka,Jaymie M. Matthews,St. Mochnacki,Piotr Orleanski,Herbert Pablo,Tahina Ramiaramanantsoa,G. Whittaker,E. Zocłońska,Konstanze Zwintz +18 more
TL;DR: In this paper, a triple system with two massive fast-rotating early B-type components is studied, and a simultaneous fit of visual and spectroscopic orbits is used to self-consistently derive the orbital parameters, and subsequently the masses, of the components.

Massive pulsating stars observed by BRITE-Constellation. I. The triple system Beta Centauri (Agena)
Andrzej Pigulski,Henryk Cugier,Adam Popowicz,Rainer Kuschnig,A. F. J. Moffat,Slavek M. Rucinski,A. Schwarzenberg-Czerny,Werner W. Weiss,Gerald Handler,Gregg A. Wade,Otto Koudelka,J. M. Matthews,Mochnacki,Piotr Orleanski,Herbert Pablo,T. Ramiaramanantsoa,G. Whittaker,E. Zocłońska,K. Zwintz +18 more
TL;DR: In this article, the authors determined the masses and detect pulsation modes in the two massive components of Beta Cen with BRITE-Constellation photometry, and used a simultaneous fit of visual and spectroscopic orbits to self-consistently derive the orbital parameters and subsequently the masses, of the components.

Alive and well: A short review about standard solar models
TL;DR: The accuracy of the physical description of the global properties of the Sun that SSMs provide has been challenged in the last decade by a number of developments in stellar spectroscopic techniques.

The Chemical Composition of the Sun
TL;DR: The solar chemical composition is an important ingredient in our understanding of the formation, structure, and evolution of both the Sun and our Solar System as discussed by the authors, and it is an essential refer...

Updated Opal Opacities
TL;DR: The updated OPAL Rosseland mean opacities for Population I stars have been presented in this paper, where the main opacity changes are increases of as much as 20% for population I stars due to the explicit inclusion of 19 metals (compared to 12 metals in the earlier calculations).
Journal ArticleDOI
Radiative atomic Rosseland mean opacity tables
TL;DR: In this paper, the authors present new radiative Rosseland mean opacity tables calculated with the OPAL code developed independently at LLNL, which allow accurate interpolation in temperature, density, hydrogen mass fraction, as well as metal mass fraction.
Journal ArticleDOI
Opacities for stellar envelopes
TL;DR: In this article, the authors defined stellar envelopes as regions of stellar interiors in which atoms exist and are not markedly perturbed by the plasma environment and adopted the criterion of mass density ρ≤0.01 g cm −3.

Helioseismology and Solar Abundances
Sarbani Basu,H. M. Antia +1 more
TL;DR: In this article, the authors review how heavy-element abundances affect solar models, how these models are tested with helioseismology, and the impact of the new abundances on standard solar models.
