Multiple populations along the asymptotic giant branch of the globular cluster M 4
C. Lardo, M. Salaris, A. Savino +3
Nearly all Galactic globular clusters host stars that display characteristic abundance anti-correlations, like the O-rich/Na-poor pattern typical of field halo stars, together with…
The Search for Multiple Populations in Magellanic Cloud Clusters II: The Detection of Multiple Populations in Three Intermediate-Age SMC Clusters
F. Niederhofer, N. Bastian, V. Kozhurina-Platais +14
This is the second paper in our series about the search for multiple populations in Magellanic Cloud star clusters using the Hubble Space Telescope. Here we report the detection of…
The Gaia-ESO Survey: Inhibited extra mixing in two giants of the open cluster Trumpler 20?
R. Smiljanic, E. Franciosini, S. Randich +32
We report the discovery of two Li-rich giants, with A(Li) ~ 1.50, in an analysis of a sample of 40 giants of the open cluster Trumpler 20 (with turnoff mass ~ 1.8 Msun). The cluste…
The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr?
J. Bouvier, A. Lanzafame, L. Venuti +37
We investigate here the lithium content of young low-mass stars in the 5~Myr-old star forming region NGC~2264 and its relationship with rotation. We combine lithium equivalent widt…
NGC6362: the least massive globular cluster with chemically distinct multiple populations
A. Mucciarelli, E. Dalessandro, D. Massari +6
We present the first measure of Fe and Na abundances in NGC 6362, a low-mass globular cluster where first and second generation stars are fully spatially mixed. A total of 160 memb…
The Gaia-ESO Survey: Sodium and aluminium abundances in giants and dwarfs - Implications for stellar and Galactic chemical evolution
R. Smiljanic, D. Romano, A. Bragaglia +40
Stellar evolution models predict that internal mixing should cause some sodium overabundance at the surface of red giants more massive than ~ 1.5--2.0 Msun. The surface aluminium a…
