The age of the Methuselah star in light of stellar evolution models with tailored abundances
C. Guillaume, G. Buldgen, A. M. Amarsi +5
Context. HD140283, or the Methuselah star, is a well-known reference object in stellar evolution. Its peculiar chemical composition, proximity and absence of reddening makes it an…
In-depth analysis of solar models with high-metallicity abundances and updated opacity tables
G. Buldgen, A. Noels, R. Scuflaire +10
Due to the high quality constraints available for the Sun, we can carry out combined analyses using neutrino, spectroscopic and helioseismic observations. Such studies lay the grou…
Apsidal motion in the massive binary HD 152248 -- Constraining the internal structure of the stars
S. Rosu, A. Noels, M. -A. Dupret +3
Apsidal motion in massive eccentric binaries offers precious information about the internal structure of the stars. This is especially true for twin binaries consisting of two near…
Seismic Solar Models from Ledoux discriminant inversions
G. Buldgen, P. Eggenberger, V. A. Baturin +6
The Sun constitutes an excellent laboratory of fundamental physics. With the advent of helioseismology, we were able to probe its internal layers with unprecedented precision. Howe…
Comprehensive stellar seismic analysis: A preliminary application of Whosglad to 16 Cygni system
M. Farnir, M-A. Dupret, S. J. A. J. Salmon +2
We present a first application of Whosglad method to the components A and B of the 16 Cygni system. The method was developed to provide a comprehensive analysis of stellar oscillat…
Combining multiple structural inversions to constrain the Solar modelling problem
G. Buldgen, S. J. A. J. Salmon, A. Noels +4
The Sun is the most studied of stars and a laboratory of fundamental physics. However, the understanding of our star is stained by the solar modelling problem which can stem from v…
