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…
Confirming the presence of second population stars and the iron discrepancy along the AGB of the globular cluster NGC 6752
A. Mucciarelli, E. Lapenna, C. Lardo +3
Asymptotic giant branch (AGB) stars in the globular cluster NGC6752 have been found to exhibit some chemical peculiarities with respect to the red giant branch (RGB) stars. A discr…
IC4499 revised: spectro-photometric evidence of small light-element variations
E. Dalessandro, C. Lardo, M. Cadelano +6
It has been suggested that IC4499 is one of the very few old globulars to not host multiple populations with light-element variations. To follow-up on this very interesting result,…
The Pristine Survey IV: Approaching the Galactic metallicity floor with the discovery of an ultra metal-poor star
Else Starkenburg, David S. Aguado, Piercarlo Bonifacio +22
The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Gala…
Gaia-ESO Survey: INTRIGOSS - A new library of High Resolution Synthetic Spectra
Mariagrazia Franchini, Carlo Morossi, Paolo Di Marcantonio +19
We present a high resolution synthetic spectral library, INTRIGOSS, designed for studying FGK stars. The library is based on atmosphere models computed with specified individual el…
The Gaia-ESO Survey: properties of newly discovered Li-rich giants
R. Smiljanic, E. Franciosini, A. Bragaglia +41
We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with evolutionary stage confirmed by CoRoT data. Atmospheric parameter…
