Gaia-Sausage-Enceladus: Lithium evolution from early red-giant-branch and main-sequence stars
C. T. Nguyen, G. Cescutti, M. M. Bennedik +3
The combination of data from the Gaia satellite and large ground-based spectroscopic surveys recently lead to a milestone understanding of our Galaxy's formation history, marked by…
The Gaia-ESO Survey: the N/O abundance ratio in the Milky Way
L. Magrini, F. Vincenzo, S. Randich +31
The abundance ratio N/O is a useful tool to study the interplay of galactic processes, e.g. star formation efficiency, time-scale of infall and outflow loading factor We aim to tra…
The Gaia -ESO Survey: Lithium enrichment histories of the Galactic thick and thin disc
Xiaoting. Fu, D. Romano, A. Bragaglia +32
Lithium abundance in most of the warm metal-poor main sequence stars shows a constant plateau (A(Li)~2.2 dex) and then the upper envelope of the lithium vs. metallicity distributio…
The -ESO Survey: the inner disk intermediate-age open cluster NGC 6802
B. Tang, D. Geisler, E. Friel +43
Milky Way open clusters are very diverse in terms of age, chemical composition, and kinematic properties. Intermediate-age and old open clusters are less common, and it is even har…
The Gaia-ESO Survey: the selection function of the Milky Way field stars
E. Stonkute, S. E. Koposov, L. M. Howes +26
The Gaia-ESO Survey was designed to target all major Galactic components (i.e., bulge, thin and thick discs, halo and clusters), with the goal of constraining the chemical and dyna…
The Gaia-ESO Survey: Characterisation of the [alpha/Fe] sequences in the Milky Way discs
G. Kordopatis, R. F. G. Wyse, G. Gilmore +30
We investigate, using the Gaia-ESO Survey internal Data-Release 2, the properties of the double sequence of the Milky Way discs (defined chemically as the high-alpha and low-alpha…
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 Galactic Thick to Thin Disc transition
A. Recio-Blanco, P. de Laverny, G. Kordopatis +36
(Abridged) We have used the atmospheric parameters, [alpha/Fe] abundances and radial velocities, determined from the Gaia-ESO Survey GIRAFFE spectra of FGK-type stars (iDR1), to pr…
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…
The Gaia-ESO Survey: Abundance ratios in the inner-disk open clusters Trumpler 20, NGC 4815, NGC 6705
L. Magrini, S. Randich, D. Romano +50
Open clusters are key tools to study the spatial distribution of abundances in the disk and their evolution with time. Using the first release of stellar parameters and abundances…
