Spectroscopic evolution of very massive stars at Z = 1/2.5 Zsun
F. Martins, A. Palacios
Stars with masses in excess of 100 Msun are observed in the Local Universe, but they remain rare objects. Because of the shape of the mass function, they are expected to be present…
Lithium depletion and angular momentum transport in F-type and G-type stars in Galactic open clusters
Thibaut Dumont, Corinne Charbonnel, Ana Palacios +1
Open clusters provide clues to understand the evolution of Li7 at the surface of low-mass stars and its possible correlation with stellar rotation, which is a challenge for both st…
Lithium depletion and angular momentum transport in solar-type stars
T. Dumont, A. Palacios, C. Charbonnel +4
Transport processes occurring in the radiative interior of solar-type stars are evidenced by the surface variation of light elements, in particular Li, and the evolution of their r…
Spectroscopic evolution of massive stars near the main sequence at low metallicity
F. Martins, A. Palacios
We present synthetic spectra and SEDs computed along evolutionary tracks at Z=1/5 Zsun and Z=1/30 Zsun, for masses between 15 and 150 Msun. We predict that the most massive stars a…
Lithium in red giant stars: Constraining non-standard mixing with large surveys in the Gaia era
C. Charbonnel, N. Lagarde, G. Jasniewicz +7
Lithium is extensively known to be a good tracer of non-standard mixing processes occurring in stellar interiors. We present the results of a new large Lithium survey in red giant…
Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking
C. Georgy, C. Charbonnel, L. Amard +8
Extended MS turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the MS turn-of…
