The Gaia-ESO Survey DR5.1 and Gaia DR3 GSP-Spec: a comparative analysis
M. Van der Swaelmen, C. Viscasillas Vazquez, L. Magrini +10
(abridged) The third data release of Gaia, has provided stellar parameters, metallicity [M/H], [α/Fe], individual abundances, broadening parameter from its RVS spectra for about 5.…
Ariel stellar characterisation II. Chemical abundances of carbon, nitrogen, and oxygen for 181 planet-host FGK dwarf stars
R. da Silva, C. Danielski, E. Delgado Mena +12
One of the ultimate goals of the ESA Ariel space mission is to shed light on the formation pathways and evolution of planetary systems in the Solar neighbourhood. Such an endeavour…
HRMOS White Paper: Science Motivation
Laura Magrini, Thomas Bensby, Anna Brucalassi +52
The High-Resolution Multi-Object Spectrograph (HRMOS) is a facility instrument that we plan to propose for the Very Large Telescope (VLT) of the European Southern Observatory (ESO)…
The Gaia-ESO Survey: new spectroscopic binaries in the Milky Way
M. Van der Swaelmen, T. Merle, S. Van Eck +14
The Gaia-ESO Survey (GES) is a large public spectroscopic survey which acquired spectra for more than 100000 stars across all major components of the Milky Way. In addition to atmo…
The role of radial migration in open cluster and field star populations with Gaia dr3
Carlos Viscasillas Vázquez, Laura Magrini, Lorenzo Spina +4
The survival time of a star cluster depends on its total mass, density, and thus size, as well as on the environment in which it was born and in which lies. Its dynamical evolution…
The Gaia-ESO Survey: homogenisation of stellar parameters and elemental abundances
A. Hourihane, P. Francois, C. C. Worley +59
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…
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…
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…
A spectroscopic quadruple as a possible progenitor of sub-Chandrasekhar Type Ia supernovae
T. Merle, A. S. Hamers, S. Van Eck +13
Binaries have received much attention as possible progenitors of Type Ia supernova (SNIa) explosions, but long-term gravitational effects in tight triple or quadruple systems could…
Ariel stellar characterisation: I -- homogeneous stellar parameters of 187 FGK planet host stars Description and validation of the method
L. Magrini, C. Danielski, D. Bossini +16
In 2020 the European Space Agency selected Ariel as the next mission to join the space fleet of observatories to study planets outside our Solar System. Ariel will be devoted to th…
The homogeneous characterisation of Ariel host stars
C. Danielski, A. Brucalassi, S. Benatti +20
The Ariel mission will characterise the chemical and thermal properties of the atmospheres of about a thousand exoplanets transiting their host star(s). The observation of such a l…
When binaries keep track of recent nucleosynthesis: The Zr - Nb pair in extrinsic stars as an s-process diagnostic
D. Karinkuzhi, S. Van Eck, A. Jorissen +9
Barium stars are s-process enriched giants. They owe their chemical peculiarities to a past mass transfer phase. During which they were polluted by their binary companion, which at…
An empirical recipe for inelastic hydrogen-atom collisions in non-LTE calculations
Rana Ezzeddine, Thibault Merle, Bertrand Plez +3
We investigate the role of hydrogen collisions in NLTE spectral line synthesis, and introduce a new general empirical recipe to determine inelastic charge transfer (CT) and bound-b…
The mass-ratio and eccentricity distributions of barium and S stars, and red giants in open clusters
Mathieu Van der Swaelmen, Henri M. J. Boffin, Alain Jorissen +1
In order to identify diagnostics distinguishing between pre- and post-mass-transfer systems, the mass-ratio distribution and period - eccentricity (P - e) diagram of barium and S s…
Sodium abundances of AGB and RGB stars in galactic globular clusters I. Analysis and results of NGC 2808
Y. Wang, F. Primas, C. Charbonnel +4
Galactic globular clusters (GC) are known to have multiple stellar populations and be characterised by similar chemical features, e.g. O-Na anti-correlation. While second-populatio…

M. Van der Swaelmen, B. Barbuy, V. Hill +4
Aims. The aim of this work is the study of abundances of the heavy elements Ba, La, Ce, Nd, and Eu in 56 bulge giants (red giant branch and red clump) with metallicities ranging fr…
Chemical abundances in LMC stellar populations. II. The bar sample
M. Van der Swaelmen, V. Hill, F. Primas +1
This paper compares the chemical evolution of the Large Magellanic Cloud (LMC) to that of the Milky Way (MW) and investigates the relation between the bar and the inner disc of the…
