Étude de l'extension des cœurs convectifs par la sismologie des étoiles sous-géantes

Autor: Noll, Anthony

Publikováno v: Astrophysique stellaire et solaire [astro-ph.SR]. Université Paul Sabatier-Toulouse III, 2021. Français. ⟨NNT : 2021TOU30266⟩

Convective cores are the hydrogen reservoirs of main-sequence stars that are more massive than around 1.2 solar masses. Therefore, their sizes strongly impact the stellar evolution. However, several physical processes, which remain poorly understood

Asteroseismology of low mass stars and coupling between oscillations and turbulent convection

Autor: Belkacem, Kevin

Publikováno v: Physique [physics]. Observatoire de Paris, 2021

Stellar physics has undergone important and rapid evolution in recent years. Part of these advances is due to stellar seismology and the advent of space-borne asteroseismology, thanks to the CoRoT and Kepler spacecraft, which have significantly incre

Previous space missions CoRoT and Kepler, current mission TESS, and mission in preparation PLATO allow the observation of millions of stars. In this thesis, we are particularly interested in red giants (evolved solar-type stars). One of the \og legac

Évolution stellaire en rotation rapide : apports de l'interférométrie et de l'astérosismologie

Autor: Bouchaud, Kevin

Publikováno v: Astrophysique stellaire et solaire [astro-ph.SR]. Observatoire de la Côte d'Azur; Observatoire de paris, 2020. Français

From the spectral lines to the frequencies of their pulsations, rapidly rotating starsexhibit signs of that rotation in all kinds of observations. Interferometry especiallyallowed us to study local effects of rotation by turning stars from points to

Asteroseismology consists in probing stellar interiors through the detection of seismic waves. Red giants are evolved low-mass stars that have exhausted hydrogen in their core. These stars are solar-type pulsators presenting mixed modes that allow us

Seismic probe of transport processes in red giants

Autor: Goupil, MarieJo

Seismic data obtained with the space photometric CoRoT and Kepler instruments have led to a unprecendently precise characterization -- in terms of masses and ages -- of a large sample of post main sequence stars (low mass subgiant and red giants). Th

Diagnostics sismiques des intérieurs stellaires avec Kepler : rotation et interfaces

Autor: Christophe, Steven

Publikováno v: Astrophysique [astro-ph]. Université Paris sciences et lettres, 2019. Français. ⟨NNT : 2019PSLEO011⟩

Asteroseismology, the study of stellar oscillations, provides a direct way to probe the physics of stellar interiors. With four years of seismic data of unprecedented quality, the Kepler mission allows us to test stellar structure and evolution model
