Chemical evolution of close massive binaries -- tidally-enhanced or tidally-suppressed mixing?
Luca Sciarini, Sophie Rosu, Sylvia Ekström +3
One of the largest source of uncertainties in the predictions of stellar models comes from the internal transport mechanisms. In close massive binaries, previous theoretical studie…
The intermediate neutron capture process. VI. Proton ingestion and i-process in rotating magnetic asymptotic giant branch stars
A. Choplin, L. Siess, S. Goriely +2
The intermediate neutron-capture process (i-process) can occur during proton ingestion events (PIEs), which may take place in the early evolutionary phases of asymptotic giant bran…
Coexisting Tayler instability-driven dynamos in radiative zones: New dynamo solution and its impacts on stellar physics
Paul Barrère, Alexis Reboul-Salze, Patrick Eggenberger +4
Recent asteroseismic observations constitute a great challenge for rotating stellar evolution models, which predict overly fast internal rotation rates when only hydrodynamic proce…
The impact of rotational mixing in intermediate-age star clusters with extended main-sequence turn-offs and extended red clumps
Lorenzo Martinelli, Andrea Miglio, Gaël Buldgen +6
The extended main-sequence turn-offs (eMSTOs) and extended red clumps (eRCs) observed in intermediate-age star clusters challenge the traditional understanding of clusters as simpl…
The fate of rotating massive stars across cosmic times
R. Hirschi, K. Goodman, G. Meynet +9
The initial mass and metallicity of stars both have a strong impact on their fate. Stellar axial rotation also has a strong impact on the structure and evolution of massive stars.…
Impact of the Tayler magnetic instability on the surface abundance of boron in massive stars
L. Asatiani, P. Eggenberger, M. Marchand +3
Context: The surface abundances of massive stars show evidence of internal mixing, while asteroseismic data suggest that efficient angular momentum (AM) transport occurs in stellar…
