Massive stars, globular clusters and elliptical galaxies
Georges Meynet, Thibaut Decressin, Corinne Charbonnel
Globular clusters as Cen and NGC 2808 appear to have a population of very He-rich stars. From a theoretical point of view, one expects the presence of He-rich stars in all glob…
Rotation-induced mixing in red giant stars
A. Palacios, C. Charbonnel, S. Talon +1
Red giant stars, both in the field and in globular clusters, present abundance anomalies that can not be explained by standard stellar evolution models. Some of these peculiarities…
Sinks of Light Elements in Stars - Part III
Corinne Charbonnel, Constantine P. Deliyannis, Marc H. Pinsonneault
The fragile light elements lithium, beryllium, and boron are easily destroyed in stellar interiors, and are thus superb probes of physical processes occuring in the outer stellar l…

The Nature of the Lithium Rich Giants. Mixing episodes on the RGB and early-AGB
Corinne Charbonnel, Suchitra C. Balachandran
We present a critical analysis of the nature of the so-called Li-rich RGB stars. For a majority of the stars, we have used Hipparcos parallaxes to determine masses and evolutionary…
Evolution and surface abundances of red giants experiencing deep mixing
Achim Weiss, Pavel A. Denissenkov, Corinne Charbonnel
We have calculated the evolution of low metallicity red giant stars under the assumption of deep mixing between the convective envelope and the hydrogen burning shell. We find that…
