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…
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: 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…
A new solar fluorine abundance and a fluorine determination in the two open clusters M 67 and NGC 6404
E. Maiorca, H. Uitenbroek, S. Uttenthaler +3
We present a new determination of the solar fluorine abundance together with abundance measurements of fluorine in two Galactic open clusters. We analyzed a sunspot spectrum, obser…
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…
s-Processing in AGB Stars Revisited. I. Does the Main Component Constrain the Neutron Source in the 13C-Pocket?
O. Trippella, M. Busso, E. Maiorca +2
Slow neutron captures at A 85 are mainly guaranteed by the reaction 13C(,n)16O in AGB stars, requiring proton injections from the envelope. These were so far assumed to…
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…
