The Future of Solar modelling: requirements for a new generation of solar models

Gael Buldgen, Gloria. Canocchi, Arthur. Le Saux +22

Helioseismology and solar modelling have enjoyed a golden era thanks to decades-long surveys from ground-based networks such as for example GONG, BiSON, IRIS and the SOHO and SDO s…

Entropy proxy inversions as tracers of the evolution of physical conditions at the base of the solar convective envelope

G. Buldgen, A. Noels, V. A. Baturin +4

The Sun is an important calibrator for the theory of stellar structure and evolution. However, the accuracy of our solar evolution models is tightly linked to the physical ingredie…

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…

Hydrogen Ionization Inside the Sun

V. A. Baturin, S. V. Ayukov, A. V. Oreshina +4

Hydrogen is the main chemical component of the solar plasma, and H-ionization determines basic properties of the first adiabatic exponent . Hydrogen ionization remarkably diff…

Heavy Elements Abundances Inferred from the First Adiabatic Exponent in the Solar Envelope

V. A. Baturin, A. V. Oreshina, G. Buldgen +5

The first adiabatic exponent profile, noted , computed along adiabatic coordinates is in the focus of our study. Under conditions of almost fully ionized hydrogen and…

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…
