The Gaia-ESO Survey: 3D dynamics of young groups and clusters from GES and Gaia EDR3
Nicholas J. Wright, R. D. Jeffries, R. J. Jackson +9
We present the first large-scale 3D kinematic study of ~2000 spectroscopically-confirmed young stars (<20 Myr) in 18 star clusters and OB associations (hereafter groups) from the c…

The Gaia-ESO Survey: No sign of multiple stellar populations in open clusters from their sodium and oxygen abundances
A. Bragaglia, V. D'Orazi, L. Magrini +9
Context: The light element (anti-)correlations shown by globular clusters (GCs) are the main spectroscopic signature of multiple stellar populations. These internal abundance varia…

The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. II. Expanded cluster sample and final membership selection
M. L. Gutiérrez Albarrán, D. Montes, H. M. Tabernero +26
The Li abundance observed in pre-main sequence and main sequence late-type stars is strongly age-dependent, but also shows a complex pattern depending on several parameters, such a…
