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…

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…

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…
