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 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…
The Gaia-ESO Survey: the most metal-poor stars in the Galactic bulge
L. Howes, M. Asplund, A. R. Casey +39
We present the first results of the EMBLA survey (Extremely Metal-poor BuLge stars with AAOmega), aimed at finding metal-poor stars in the Milky Way bulge, where the oldest stars s…
On the Relative Ages of the -Rich and -Poor Stellar Populations in the Galactic Halo
Keith Hawkins, Paula Jofre, Gerry Gilmore +1
We study the ages of -rich and -poor stars in the halo using a sample of F and G dwarfs from the Sloan Digital Sky Survey (SDSS). To separate stars based on [/Fe], we have…
Gaia-ESO Survey: The analysis of high-resolution UVES spectra of FGK-type stars
R. Smiljanic, A. J. Korn, M. Bergemann +99
The Gaia-ESO Survey is obtaining high-quality spectroscopic data for about 10^5 stars using FLAMES at the VLT. UVES high-resolution spectra are being collected for about 5000 FGK-t…
The Gaia-ESO Survey: the chemical structure of the Galactic discs from the first internal data release
Š. Mikolaitis, V. Hill, A. Recio-Blanco +31
Most high-resolution spectroscopic studies of the Galactic discs were mostly confined to objects in the solar vicinity. Here we aim at enlarging the volume in which individual chem…
The Gaia-ESO Survey: metallicity and kinematic trends in the Milky Way bulge
A. Rojas-Arriagada, A. Recio-Blanco, V. Hill +30
(Abridged) We analyzed the stellar parameters and radial velocities of ~1200 stars in five bulge fields as determined from the Gaia-ESO survey data (iDR1). We use VISTA Variables i…
The Gaia-ESO Survey: Stellar content and elemental abundances in the massive cluster NGC 6705
T. Cantat-Gaudin, A. Vallenari, S. Zaggia +52
Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple population…
The Gaia-ESO Survey: the first abundance determination of the pre-main-sequence cluster Gamma Velorum
L. Spina, S. Randich, F. Palla +36
Knowledge of the abundance distribution of star forming regions and young clusters is critical to investigate a variety of issues, from triggered star formation and chemical enrich…
Empirical classification of VLT/Giraffe stellar spectra in the wavelength range 6440-6810 A in the gamma Vel cluster, and calibration of spectral indices
F. Damiani, L. Prisinzano, G. Micela +23
We study spectral diagnostics available from optical spectra with R=17000 obtained with the VLT/Giraffe HR15n setup, using observations from the Gaia-ESO Survey, on the gamma Vel y…
The Gaia-ESO Survey: Properties of the intermediate age open cluster NGC 4815
E. D. Friel, P. Donati, A. Bragaglia +34
NGC 4815 is a populous ~500 Myr open cluster at a Galactocentric radius of 7 kpc observed in the first six months of the Gaia-ESO Survey. Located in the inner Galactic disk, NGC 48…
The Gaia-ESO Survey: processing of the FLAMES-UVES spectra
G. G. Sacco, L. Morbidelli, E. Franciosini +49
The Gaia-ESO Survey is a large public spectroscopic survey that aims to derive radial velocities and fundamental parameters of about 10^5 Milky Way stars in the field and in cluste…
The Gaia-ESO Survey: Kinematic structure in the Gamma Velorum Cluster
R. D. Jeffries, R. J. Jackson, M. Cottaar +27
Context: A key science goal of the Gaia-ESO survey (GES) is to use the kinematics of low-mass stars in young clusters to probe their dynamical histories and how they populate the f…
The Gaia-ESO Survey: radial metallicity gradients and age-metallicity relation of stars in the Milky Way disk
M. Bergemann, G. Ruchti, A. Serenelli +42
We study the relationship between age, metallicity, and alpha-enhancement of FGK stars in the Galactic disk. The results are based upon the analysis of high-resolution UVES spectra…
