Investigating the impact of Solar Fusion III reaction rates on helioseismic constraints and solar neutrino fluxes

T. Sandron, G. Buldgen, A. Noels +2

Nuclear reaction rates are crucial ingredients of solar and stellar models, they directly impact the duration of the life of stars and the energy they produce. In the solar case, t…

A data-driven estimate of the protosolar helium mass fraction

G. Buldgen, M. Kunitomo, A. Noels +3

The protosolar helium mass-fraction is a key ingredient of solar, planetary models and enrichment laws. However, the assumed values often rely on simplified descriptions of the tra…

Detailed theoretical analysis of core Helium-burning stars: Mixed mode patterns I. Impact of the He-flash discontinuity and of induced semi-convection

L. Panier, G. Buldgen, M. Matteuzzi +4

Space missions like CoRoT, Kepler, and TESS have made asteroseismology a powerful probe of stellar interiors. Red giants are key targets thanks to their rich mixed-mode oscillation…

Asteroseismic modelling of Kepler Legacy stars including lithium depletion

G. Buldgen, J. Bétrisey, C. Pezzotti +2

Context. The Kepler Legacy sample is, to this day, the sample of solar-like oscillators with the most exquisite asteroseismic data. In this work, we carry out a detailed modelling…

The impact of the transport of chemicals and electronic screening on helioseismic and neutrino observations in solar models

Morgan Deal, Gaël Buldgen, Louis Manchon +3

The transport of chemical elements in stellar interiors is one of the greatest sources of uncertainties of solar and stellar modelling. The Sun, with its exquisite spectroscopic, h…

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…

Constraints on the properties of macroscopic transport in the Sun from combined lithium and beryllium depletion

G. Buldgen, A. Noels, A. M. Amarsi +5

Context. The Sun is a privileged laboratory of stellar evolution, thanks to the quality and complementary nature of available constraints. Using these observations, we are able to…

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…

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…
