Constraining the efficiency of angular momentum transport with asteroseismology of red giants: the effect of stellar mass
P. Eggenberger, N. Lagarde, A. Miglio +12
Context: Constraints on the internal rotation of red giants are now available thanks to asteroseismic observations. Preliminary comparisons with rotating stellar models indicate th…
The advanced stages of stellar evolution: impact of mass loss, rotation, and link with B[e] stars
Cyril Georgy, Hideyuki Saio, Sylvia Ekström +1
In this paper, we discuss some consequences of rotation and mass loss on the evolved stages of massive star evolution. The physical reasons of the time evolution of the surface vel…
High surface magnetic field in red giants as a new signature of planet engulfment?
Giovanni Privitera, Georges Meynet, Patrick Eggenberger +6
Context. Red-giant stars may engulf planets. This may increase the rotation rate of their convective envelope, which could lead to strong dynamo-triggered magnetic fields. Aims. We…
Star-planet interactions: II. Is planet engulfment the origin of fast rotating red giants?
Giovanni Privitera, Georges Meynet, Patrick Eggenberger +3
Context. Fast rotating red giants in the upper part of the red giant branch have surface velocities that cannot be explained by single star evolution. Aims. We check whether tides…
Evolution of long-lived globular cluster stars III. Effect of the initial helium spread on the position of stars in a synthetic Hertzsprung-Russell diagram
William Chantereau, Corinne Charbonnel, Georges Meynet
Context. Globular clusters host multiple populations of long-lived low-mass stars whose origin remains an open question. Several scenarios have been proposed to explain the associa…
Constraints on CEMP-no progenitors from nuclear astrophysics
Arthur Choplin, André Maeder, Georges Meynet +1
The CEMP-no stars are long-lived small mass stars presenting a very low iron content and overabundances of carbon with no sign or only very weak signs for the presence of s- or r-e…
