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 Gaia-ESO Survey: Matching Chemo-Dynamical Simulations to Observations of the Milky Way
B. B. Thompson, C. G. Few, M. Bergemann +39
The typical methodology for comparing simulated galaxies with observational surveys is usually to apply a spatial selection to the simulation to mimic the region of interest covere…
The transiting multi-planet system HD3167: a 5.7 MEarth Super-Earth and a 8.3 MEarth mini-Neptune
Davide Gandolfi, Oscar Barragán, Artie P. Hatzes +42
HD3167 is a bright (V=8.9 mag) K0V star observed by the NASA's K2 space mission during its Campaign 8. It has been recently found to host two small transiting planets, namely, HD31…
The Gaia-ESO Survey: Exploring the complex nature and origins of the Galactic bulge populations
A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +36
Abridged: We used the fourth internal data release of the Gaia-ESO survey to characterize the bulge chemistry, spatial distribution, kinematics, and to compare it chemically with t…
The Gaia-ESO Survey: radial distribution of abundances in the Galactic disc from open clusters and young field stars
L. Magrini, S. Randich, G. Kordopatis +44
The spatial distribution of elemental abundances in the disc of our Galaxy gives insights both on its assembly process and subsequent evolution, and on the stellar nucleogenesis of…
Gaia-ESO Survey: global properties of clusters Trumpler 14 and 16 in the Carina Nebula
F. Damiani, A. Klutsch, R. D. Jeffries +31
We present the first extensive spectroscopic study of the global population in star clusters Trumpler~16, Trumpler~14 and Collinder~232 in the Carina Nebula, using data from the Ga…
The Gaia-ESO Survey: the present-day radial metallicity distribution of the Galactic disc probed by pre-main-sequence clusters
L. Spina, S. Randich, L. Magrini +35
The radial metallicity distribution in the Galactic thin disc represents a crucial constraint for modelling disc formation and evolution. Open clusters allow us to derive both the…
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…
K2-139 b: a low-mass warm Jupiter on a 29-day orbit transiting an active K0 V star
O. Barragán, D. Gandolfi, A. M. S. Smith +27
We announce the discovery of K2-139 b (EPIC 218916923 b), a transiting warm-Jupiter (=54725 K) on a 29-day orbit around an active (log =…
The Gaia-ESO Survey: Structural and dynamical properties of the young cluster Chamaeleon I
G. G. Sacco, L. Spina, S. Randich +44
The young (~2 Myr) cluster Chamaeleon I is one of the closest laboratories to study the early stages of star cluster dynamics in a low-density environment. We studied its structura…
Chemical characterization of the globular cluster NGC 5634 associated to the Sagittarius dwarf spheroidal galaxy
Eugenio Carretta, Angela Bragaglia, Sara Lucatello +5
As part of our on-going project on the homogeneous chemical characterization of multiple stellar populations in globular clusters (GCs), we studied NGC 5634, associated to the Sagi…
