The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. II. Expanded cluster sample and final membership selection
M. L. Gutiérrez Albarrán, D. Montes, H. M. Tabernero +26
The Li abundance observed in pre-main sequence and main sequence late-type stars is strongly age-dependent, but also shows a complex pattern depending on several parameters, such a…
Binary origin of blue straggler stars in Galactic star clusters
M. J. Rain, M. S. Pera, G. Perren +5
Building on the recent release of a new \emph{Gaia}-based blue straggler star catalog in Galactic open star clusters (OCs), we explored the properties of these stars in a cluster s…
Gaia-ESO Survey: Role of magnetic activity and starspots on pre-main sequence lithium evolution
E. Franciosini, E. Tognelli, S. Degl'Innocenti +24
Pre-main sequence models with inflated radii are needed to simultaneously reproduce the colour-magnitude diagram and the lithium depletion pattern in young open clusters. We tested…
The Gaia-ESO Survey: Galactic evolution of lithium at high metallicity
S. Randich, L. Pasquini, E. Franciosini +20
Reconstructing the Galactic evolution of lithium (Li) is the main tool used to constrain the source(s) of Li enrichment in the Galaxy. Recent results have suggested a decline in Li…
The Gaia-ESO Survey: Galactic evolution of sulphur and zinc
S. Duffau, E. Caffau, L. Sbordone +48
Due to their volatile nature, when sulfur and zinc are observed in external galaxies, their determined abundances represent the gas-phase abundances in the interstellar medium. Thi…
The Gaia-ESO Survey. Mg-Al anti-correlation in iDR4 globular clusters
E. Pancino, the GES collaboration
We use Gaia-ESO Survey iDR4 data to explore the Mg-Al anti-correlation in globular clusters, that were observed as calibrators, as a demonstration of the quality of Gaia-ESO Survey…
The Gaia-ESO Survey: the inner disk, intermediate-age open cluster Trumpler 23
J. C. Overbeek, E. D. Friel, P. Donati +33
Context: Trumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a Rgc ~6 kpc. It is in a crowded field very close to the Galactic plane and…
The Gaia-ESO Survey: calibration strategy
E. Pancino, the Gaia-ESO Survey collaboration
The Gaia-ESO survey (GES) is now in its fifth and last year of observations, and has already produced tens of thousands of high-quality spectra of stars in all Milky Way components…
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…
The Gaia-ESO Survey: Revisiting the Li-rich giant problem
A. R. Casey, G. Ruchti, T. Masseron +48
The discovery of lithium-rich giants contradicts expectations from canonical stellar evolution. Here we report on the serendipitous discovery of 20 Li-rich giants observed during t…
The Gaia-ESO Survey: membership and Initial Mass Function of the Gamma Velorum cluster
L. Prisinzano, F. Damiani, G. Micela +23
Understanding the properties of young open clusters, such as the Initial Mass Function (IMF), star formation history and dynamic evolution, is crucial to obtain reliable theoretica…
The Gaia-ESO Survey: Stellar radii in the young open clusters NGC 2264, NGC 2547 and NGC 2516
R. J. Jackson, R. D. Jeffries, S. Randich +10
Rapidly rotating, low-mass members of eclipsing binary systems have measured radii significantly larger than predicted by standard models. It has been proposed that magnetic activi…
The Gaia-ESO Survey: Discovery of a spatially extended low-mass population in the Vela OB2 association
G. G. Sacco, R. D. Jeffries, S. Randich +28
The nearby (distance~350-400 pc), rich Vela OB2 association, includes Velorum, one of the most massive binaries in the solar neighbourhood and an excellent laboratory for inv…
New insights on Ba over-abundance in open clusters. Evidence for the intermediate neutron-capture process at play?
T. Mishenina, M. Pignatari, G. Carraro +6
Recently an increasing number of studies were devoted to measure the abundances of neutron-capture elements heavier than iron in stars belonging to Galactic Open Clusters (OCs). OC…
