Nucleosynthesis in Rotating massive stars and Abundances in the Early Galaxy (2009)
Meynet, Georges, Hirschi, Raphael, Ekstrom, Sylvia, Maeder, Andre, Georgy, Cyril, Eggenberger, Patrick, ...
We discuss three effects of axial rotation at low metallicity. The first one is the mixing of the chemical species which is predicted to be more efficient in low metallicity environments. A...
Models for Pop I stars: implications for age determinations (2008)
Meynet, Georges, Eggenberger, Patrick, Mowlavi, Nami, Maeder, Andre
Starting from a few topical astrophysical questions which require the knowledge of the age of Pop I stars, we discuss the needed precision on the age in order to make progresses in these areas of...
Arentoft, Torben, Kjeldsen, Hans, Bedding, Timothy R., Bazot, Michael, Christensen-Dalsgaard, Joergen, Dall, Thomas H., ...
We have carried out a multi-site campaign to measure oscillations in the F5 star Procyon A. We obtained high-precision velocity observations over more than three weeks with eleven telescopes, with...
Populations of massive stars in galaxies, implications for the stellar evolution theory (2007)
Meynet, Georges, Eggenberger, Patrick, Maeder, Andre
After a brief review of the observational evidences indicating how the populations of Be stars, red/blue supergiants, Wolf-Rayet stars vary as a function of metallicity, we discuss the implications...

Asteroseismology is a powerful method for determining fundamental properties of stars. We report the first application to a metal-poor object, namely the subgiant star nu Ind. We measured precise...

Seismology and activity of the F type star HD 49933 (2005)
Mosser, Benoît, Bouchy, François, Catala, Claude, Michel, Eric, Samadi, Reza, Thévenin, Frédéric, ...
A 10-night asteroseismic observation programme has been conducted in January 2004 with the spectrometer Harps at the ES0 3.6-m telescope. The selected target, the 6th magnitude F5V star HD 49933, was...
