An ancient system hidden in the Galactic plane?
Federico Sestito, Emma Fernandez-Alvar, Rebecca Brooks +19
We analyse high signal-to-noise ESPaDOnS/CFHT spectra of 20 very metal-poor stars (VMP; [Fe/H]~) in the solar neighbourhood (within kpc), selected to be on planar or…
The Pristine Inner Galaxy Survey (PIGS) IX. The largest detailed chemical analysis of very metal-poor stars in the Sagittarius dwarf galaxy
Federico Sestito, Sara Vitali, Paula Jofre +16
The most metal-poor stars provide valuable insights into the early chemical enrichment history of a system, carrying the chemical imprints of the first generations of supernovae. T…

The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
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 Pristine Inner Galaxy Survey (PIGS) IV: A photometric metallicity analysis of the Sagittarius dwarf spheroidal galaxy
Sara Vitali, Anke Arentsen, Else Starkenburg +15
We present a comprehensive metallicity analysis of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) using photometry. We base our member selection on EDR3…
Differential abundances of open clusters and their tidal tails: chemical tagging and chemical homogeneity
L. Casamiquela, Y. Tarricq, C. Soubiran +4
Well studied Open Clusters (OCs) in the Solar neighbourhood are used as reference objects to test galactic and stellar theories. For that purpose their chemical composition needs t…
The Gaia-ESO survey: Calibrating a relationship between Age and the [C/N] abundance ratio with open clusters
G. Casali, L. Magrini, E. Tognelli +51
In the era of large high-resolution spectroscopic surveys, high-quality spectra can contribute to our understanding of the Galactic chemical evolution, providing chemical abundance…
Ages and kinematics of chemically selected, accreted Milky Way halo stars
Payel Das, Keith Hawkins, Paula Jofre
We exploit the [Mg/Mn]-[Al/Fe] chemical abundance plane to help identify nearby halo stars in the 14th data release from the APOGEE survey that have been accreted on to the Milky W…
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: the origin and evolution of s-process elements
L. Magrini, L. Spina, S. Randich +45
Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations, giving important constraints to stell…
The Gaia-ESO Survey: Churning through the Milky Way
M. R. Hayden, A. Recio-Blanco, P. de Laverny +29
We attempt to determine the relative fraction of stars that have undergone significant radial migration by studying the orbital properties of metal-rich ([Fe/H]) stars within…
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 Gaia-ESO Survey: dynamics of ionized and neutral gas in the Lagoon nebula (M8)
F. Damiani, R. Bonito, L. Prisinzano +12
We present a spectroscopic study of the dynamics of the ionized and neutral gas throughout the Lagoon nebula (M8), using VLT/FLAMES data from the Gaia-ESO Survey. We explore the co…
The Gaia-ESO Survey: Dynamical models of flattened, rotating globular clusters
Sarah M. R. Jeffreson, Jason L. Sanders, N. W. Evans +12
We present a family of self-consistent axisymmetric rotating globular cluster models which are fitted to spectroscopic data for NGC 362, NGC 1851, NGC 2808, NGC 4372, NGC 5927 and…
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…
The Gaia-ESO Survey: low-alpha element stars in the Galactic Bulge
A. Recio-Blanco, A. Rojas-Arriagada, P. de Laverny +17
We take advantage of the Gaia-ESO Survey iDR4 bulge data to search for abundance anomalies that could shed light on the composite nature of the Milky Way bulge. The alpha-elements…
