The SB9 catalogue: status, comparison with non-single stars from Gaia DR3 and evolution to SBX
T. Merle, A. Jorissen, S. Alexandre +9
The Ninth Catalogue of Spectroscopic Binary Orbits (SB9) is a comprehensive compilation of spectroscopic binaries (SBs) with orbital parameters sourced from literature, comprising…
MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
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: Lithium abundances in open cluster Red Clump stars
L. Magrini, R. Smiljanic, E. Franciosini +25
It has recently been suggested that all giant stars with mass below 2 suffer an episode of surface lithium enrichment between the tip of the red giant branch (RGB) and…
The Gaia-ESO Survey: A new approach to chemically characterising young open clusters II. Abundances of the neutron-capture elements Cu, Sr, Y, Zr, Ba, La, and Ce
M. Baratella, V. D'Orazi, V. Sheminova +32
Young open clusters (t<200 Myr) have been observed to exhibit several peculiarities in their chemical compositions, from a slightly sub-solar iron content, super-solar abundances o…
The Gaia-ESO survey: Mixing processes in low-mass stars traced by lithium abundance in cluster and field stars
L. Magrini, N. Lagarde, C. Charbonnel +42
We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from th…
The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. I. Cluster age range and initial membership selections
M. L. Gutiérrez Albarrán, D. Montes, M. Gómez Garrido +33
Previous studies of open clusters have shown that lithium depletion is not only strongly age dependent but also shows a complex pattern with other parameters that is not yet unders…
The GALAH survey: Multiple stars and our Galaxy. I. A comprehensive method for deriving properties of FGK binary stars
G. Traven, S. Feltzing, T. Merle +24
Binary stellar systems form a large fraction of the Galaxy's stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be corre…
The Gaia-ESO Survey: a new approach to chemically characterising young open clusters
M. Baratella, V. D'Orazi, G. Carraro +33
Open clusters (OCs) are recognised as excellent tracers of Galactic thin-disc properties. At variance with intermediate-age and old OCs, for which a significant number of studies i…
The Gaia-ESO Survey: Carbon abundance in the Galactic thin and thick disks
Mariagrazia Franchini, Carlo Morossi, Paolo Di Marcantonio +24
This paper focuses on carbon that is one of the most abundant elements in the Universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution.…
The Belgian repository of fundamental atomic data and stellar spectra (BRASS) II. Quality assessment of atomic data for unblended lines in FGK stars
M. Laverick, A. Lobel, P. Royer +7
Fundamental atomic transition parameters, such as oscillator strengths and wavelengths, play a key role in modelling and understanding the chemical composition of stars in the univ…
Investigating the population of Galactic star formation regions and star clusters within a Wide-Fast-Deep Coverage of the Galactic Plane
L. Prisinzano, L. Magrini, F. Damiani +32
One of the aims of LSST is to perform a systematic survey of star clusters and star forming regions (SFRs) in our Galaxy. In particular, the observations obtained with LSST will ma…
Sodium abundances of AGB and RGB stars in Galactic globular clusters II. Analysis and results of NGC 104, NGC 6121 and NGC 6809
Y. Wang, F. Primas, C. Charbonnel +4
We analyzed the high-resolution spectra of a large sample of AGB and RGB stars in the Galactic globular clusters (GCs) NGC 104, NGC 6121, and NGC 6809 obtained with FLAMES/GIRAFFE…
The Gaia-ESO Survey: double, triple and quadruple-line spectroscopic binary candidates
T. Merle, S. Van Eck, A. Jorissen +35
The Gaia-ESO Survey (GES) is a large spectroscopic survey that provides a unique opportunity to study the distribution of spectroscopic multiple systems among different populations…
