A More Complex Than Expected Formation History of the Milky Way's Last Major Merger
Hai-Feng Wang, Guan-Yu Wang, Giovanni Carraro +3
The GaiaSausageEnceladus (GSE) structure, widely recognized as the most recent major accretion event experienced by our Galaxy, is traditionally interpreted as the remnant of…
Photometric Identification of Unresolved Binary Stars in Nearby Open Star Clusters
Varvara O. Mikhnevich, Anastasiia Plotnikova, Giovanni Carraro +1
This paper introduces a new method to search for unresolved binary stars in open star clusters. The work aims at improving the approach introduced previously, which employs the (H-…
Counting mass with Gaia: Mass Density of stars and stellar remnants in the solar neighborhood
Artem Lutsenko, Giovanni Carraro, Vladimir Korchagin +2
In the light of new full-sky surveys, many attempts of creating a consistent Galactic model were made. The main interest is to estimate the still poorly understood dark matter cont…
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…
Velocity Dispersion of the open cluster NGC 2571 by Radial Velocities and Proper Motions
Maxim V. Kulesh, Aleksandra E. Samirkhanova, Giovanni Carraro +3
We use a Kernel Density Estimator method to evaluate the stellar velocity dispersion in the open cluster NGC 2571. We derive the 3-D velocity dispersion using both proper motions a…
Binary origin of blue straggler stars in Galactic star clusters
M. J. Rain, M. S. Pera, G. Perren +5
Building on the recent release of a new \emph{Gaia}-based blue straggler star catalog in Galactic open star clusters (OCs), we explored the properties of these stars in a cluster s…
Binary fraction in Galactic star clusters: FSR 866, NGC 1960, and STOCK 2
Lidia Yalyalieva, Alexandr Chemel, Giovanni Carraro +1
The study of binary stars in different astronomical environments offers insights into the dynamical state of the hosting stellar systems. The Binary Fraction in fact plays a crucia…
Gaia-ESO Survey: Role of magnetic activity and starspots on pre-main sequence lithium evolution
E. Franciosini, E. Tognelli, S. Degl'Innocenti +24
Pre-main sequence models with inflated radii are needed to simultaneously reproduce the colour-magnitude diagram and the lithium depletion pattern in young open clusters. We tested…
The Gaia-ESO Survey: Galactic evolution of lithium from iDR6
D. Romano, L. Magrini, S. Randich +31
We exploit the unique characteristics of a sample of open clusters (OCs) and field stars for which high-precision 7Li abundances and stellar parameters are homogeneously derived by…
The Gaia-ESO Survey: Galactic evolution of lithium at high metallicity
S. Randich, L. Pasquini, E. Franciosini +20
Reconstructing the Galactic evolution of lithium (Li) is the main tool used to constrain the source(s) of Li enrichment in the Galaxy. Recent results have suggested a decline in Li…
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: Galactic evolution of sulphur and zinc
S. Duffau, E. Caffau, L. Sbordone +48
Due to their volatile nature, when sulfur and zinc are observed in external galaxies, their determined abundances represent the gas-phase abundances in the interstellar medium. Thi…
The Gaia-ESO Survey. Mg-Al anti-correlation in iDR4 globular clusters
E. Pancino, the GES collaboration
We use Gaia-ESO Survey iDR4 data to explore the Mg-Al anti-correlation in globular clusters, that were observed as calibrators, as a demonstration of the quality of Gaia-ESO Survey…
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…
The -ESO Survey: the inner disk intermediate-age open cluster NGC 6802
B. Tang, D. Geisler, E. Friel +43
Milky Way open clusters are very diverse in terms of age, chemical composition, and kinematic properties. Intermediate-age and old open clusters are less common, and it is even har…
The Gaia-ESO Survey: the inner disk, intermediate-age open cluster Trumpler 23
J. C. Overbeek, E. D. Friel, P. Donati +33
Context: Trumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a Rgc ~6 kpc. It is in a crowded field very close to the Galactic plane and…
The Gaia-ESO Survey: calibration strategy
E. Pancino, the Gaia-ESO Survey collaboration
The Gaia-ESO survey (GES) is now in its fifth and last year of observations, and has already produced tens of thousands of high-quality spectra of stars in all Milky Way components…
The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr?
J. Bouvier, A. Lanzafame, L. Venuti +37
We investigate here the lithium content of young low-mass stars in the 5~Myr-old star forming region NGC~2264 and its relationship with rotation. We combine lithium equivalent widt…
The Gaia-ESO Survey: Revisiting the Li-rich giant problem
A. R. Casey, G. Ruchti, T. Masseron +48
The discovery of lithium-rich giants contradicts expectations from canonical stellar evolution. Here we report on the serendipitous discovery of 20 Li-rich giants observed during t…
