C/C of Kepler giant stars: the missing piece of the mixing puzzle
N. Lagarde, R. Minkeviciute, A. Drazdauskas +6
Despite a rich observational background, few spectroscopic studies have dealt with the measurement of the carbon isotopic ratio in giant stars. However, it is a key element in unde…
Observational signatures of lithium depletion in the metal-poor globular cluster NGC6397
K. Lind, F. Primas, C. Charbonnel +2
The "stellar" solution to the cosmological lithium problem proposes that surface depletion of lithium in low-mass, metal-poor stars can reconcile the lower abundances found for Gal…
Beryllium abundances along the evolutionary sequence of the open cluster IC 4651
Rodolfo Smiljanic, L. Pasquini, C. Charbonnel +1
The simultaneous investigation of Li and Be in stars is a powerful tool in the study of the evolutionary mixing processes. Here, we present beryllium abundances in stars along the…
Beryllium abundances along the evolutionary sequence of the open cluster IC 4651 - New test for hydrodynamical stellar models
Rodolfo Smiljanic, Luca Pasquini, Corinne Charbonnel +1
[abridged] Previous analyses of lithium abundances in main sequence and red giant stars have revealed the action of mixing mechanisms other than convection in stellar interiors. Be…
CNONa and 12C/13C in giants of 10 open clusters
R. Smiljanic, R. Gauderon, P. North +3
Evolved low-mass stars of a wide range of metallicity bear signatures of a non-standard mixing event in their surface abundances of Li, C, and N, and in their 12C/13C ratio. A Na o…
Detailed chemical composition of the open cluster IC 4651: The iron peak, alpha elements, and Li
L. Pasquini, S. Randich, M. Zoccali +3
We present a detailed chemical analysis of 22 stars along the colour-magnitude sequence of the intermediate-age (1.7 Gyr) open cluster IC 4651. We find for the cluster a well-defin…
