The Gaia-ESO Survey is a public spectroscopic survey that has targeted stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering i…
A Jupiter analogue and a cold Super-Neptune orbiting the solar-twin star HIP 104045
Thiago Ferreira, Jorge Meléndez, Diego Lorenzo-Oliveira +3
We present the discovery of two planets around the solar twin HIP 104045 via radial velocity data obtained with the ESO/HARPS spectrograph as part of the Solar Twin Planet Search o…
The Gaia-ESO survey: mapping the shape and evolution of the radial abundance gradients with open clusters
L. Magrini, C. Viscasillas Vazquez, L. Spina +27
The spatial distribution of elemental abundances and their time evolution are among the major constraints to disentangle the scenarios of formation and evolution of the Galaxy. We…
Stellar Population Astrophysics (SPA) with the TNG. alpha-elements, lithium, sodium and aluminum in 16 open clusters
R. Zhang, S. Lucatello, A. Bragaglia +13
Exploring the Galactic chemical evolution and enrichment scenarios with open clusters allows us to understand the history of the Milky Way disk. High-resolution spectra of OCs are…
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products
G. Gilmore, S. Randich, C. C. Worley +165
The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100,000 stars, including large representat…
The Gaia-ESO survey: placing constraints on the origin of r-process elements
M. Van der Swaelmen, C. Viscasillas Vázquez, G. Cescutti +19
A renewed interest about the origin of \emph{r}-process elements has been stimulated by the multi-messenger observation of the gravitational event GW170817, with the detection of b…
Astro-photometric study of M37 with Gaia and wide-field ugi-imaging
M. Griggio, L. R. Bedin, R. Raddi +15
We present an astrometric and photometric wide-field study of the Galactic open star cluster M37 (NGC 2099). The studied field was observed with ground-based images covering a regi…
The cerium content of the Milky Way as revealed by Gaia DR3 GSP-Spec abundances
G. Contursi, P. de Laverny, A. Recio-Blanco +12
The recent Gaia Third Data Release contains a homogeneous analysis of millions of high-quality Radial Velocity Spectrometer (RVS) stellar spectra by the GSP-Spec module. This led t…
Gaia Data Release 3: Chemical cartography of the Milky Way
Gaia Collaboration, A. Recio-Blanco, G. Kordopatis +447
Gaia DR3 opens a new era of all-sky spectral analysis of stellar populations thanks to the nearly 5.6 million stars observed by the RVS and parametrised by the GSP-spec module. The…
The Gaia-ESO Public Spectroscopic Survey: Implementation, data products, open cluster survey, science, and legacy
S. Randich, G. Gilmore, L. Magrini +161
In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim of delivering stellar parameters and elemental abundances f…
The Gaia-ESO Survey: Chemical tagging in the thin disk. Open clusters blindly recovered in the elemental abundance space
L. Spina, L. Magrini, G. G. Sacco +14
The chemical makeup of a star provides the fossil information of the environment where it formed. Under this premise, it should be possible to use chemical abundances to tag stars…
The Gaia-ESO Survey: Age-chemical-clock relations spatially resolved in the Galactic disc
C. Viscasillas Vázquez, L. Magrini, G. Casali +33
The last decade has seen a revolution in our knowledge of the Galaxy thanks to the Gaia and asteroseismic space missions and the ground-based spectroscopic surveys. To complete thi…
Mapping the Galactic Metallicity Gradient with Open Clusters: The State-of-the-Art and Future Challenges
Lorenzo Spina, Laura Magrini, Katia Cunha
In this paper, we make use of data collected for open cluster members by high-resolution spectroscopic surveys and programmes (i.e., APOGEE, Gaia-ESO, GALAH, OCCASO, and SPA). Thes…

Stock 2 is a little-studied open cluster that shows an extended main-sequence turnoff (eMSTO). In order to investigate this phenomenon and characterise the cluster itself we perfor…
Chemical evidence for planetary ingestion in a quarter of Sun-like stars
Lorenzo Spina, Parth Sharma, Jorge Meléndez +5
Stellar members of binary systems are formed from the same material, therefore they should be chemically identical. However, recent high-precision studies have unveiled chemical di…
