The Gaia-ESO Survey: Chromospheric Emission, Accretion Properties, and Rotation in Velorum and Chamaeleon I
A. Frasca, K. Biazzo, A. C. Lanzafame +33
We use the fundamental parameters delivered by the GES consortium in the first internal data release to select the members of Vel and Cha I among the UVES and GIRAFFE spectrosc…
The Gaia-ESO Survey: Kinematics of seven Galactic globular clusters
C. Lardo, E. Pancino, M. Bellazzini +24
The Gaia-ESO survey is a large public spectroscopic survey aimed at investigating the origin and formation history of our Galaxy by collecting spectroscopy of representative sample…
The Gaia-ESO Survey: CNO abundances in the open clusters Trumpler 20, NGC 4815, and NGC 6705
G. Tautvaišienė, A. Drazdauskas, Š. Mikolaitis +30
Aim of this work is to determine C, N, and O abundances in stars of Galactic open clusters of the Gaia-ESO survey and to compare the observed abundances with those predicted by cur…
The old, metal-poor, anticentre open cluster Trumpler 5
P. Donati, G. Cocozza, A. Bragaglia +4
As part of a long term programme, we analyse the evolutionary status and properties of the old and populous open cluster Trumpler 5 (Tr 5), located in the Galactic anticentre direc…
The Na-O anticorrelation in horizontal branch stars. V. NGC 6723
R. G. Gratton, S. Lucatello, A. Sollima +7
We used FLAMES+GIRAFFE (Medusa mode) at the VLT to obtain moderately high resolution spectra for 30 red horizontal branch (RHB) stars, 4 RR Lyrae variables, and 17 blue horizontal…
The Gaia-ESO Survey: α-abundances of metal-poor stars
R. Jackson-Jones, P. Jofré, K. Hawkins +21
We performed a detailed study of the ratio of low-α to high-α stars in the Galactic halo as observed by the Gaia-ESO Survey. Using a sample of 381 metal-poor stars from the second…
