On the theoretical instability strips of γ-Doradus stars including the effect of the metallicity and rotation

L. Fellay, M. -A. Dupret

Recent space missions such as Kepler have provided large-scale observations of the γ-Doradus instability strips (IS), which can be used to constrain models and explore their limita…

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…

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…

Resonance locking and tidal evolution in rotating γ-Doradus binaries

L. Fellay, M. -A. Dupret, P. A. Kołaczek-Szymański

In binary systems, studying tidal interactions is key to understanding the evolution of binary populations. The primary dissipation process occurring in stars with radiative envelo…

Asteroseismology of HD 23734, HD 68703, and HD 73345 using K2-TESS Space-based Photometry and High-resolution Spectroscopy

Santosh Joshi, Athul Dileep, Eugene Semenko +14

In this paper, we present a comprehensive study of three stars, HD 23734, HD 68703, and HD 73345, which were previously observed as chemically peculiar candidates within the Nainit…

Parametric models of core-helium-burning stars: structural glitches near the core

Massimiliano Matteuzzi, Gaël Buldgen, Marc-Antoine Dupret +3

Understanding the internal structure of core helium burning (CHeB) stars is crucial for evaluating transport processes in nuclear-burning regions, constructing accurate stellar pop…
