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…
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 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…
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: 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: 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: Characterisation of the [alpha/Fe] sequences in the Milky Way discs
G. Kordopatis, R. F. G. Wyse, G. Gilmore +30
We investigate, using the Gaia-ESO Survey internal Data-Release 2, the properties of the double sequence of the Milky Way discs (defined chemically as the high-alpha and low-alpha…
Insights into the properties of the Local (Orion) spiral arm. NGC 2302: First results and description of the program
E. Costa, A. Moitinho, M. Radiszc +4
The spiral structure of the Milky Way is highly uncertain and is the subject of much discussion nowadays. We present the first result from a program that determines the properties…
The Gaia-ESO Survey: Kinematics of seven Galactic globular clusters
C. Lardo, E. Pancino, M. Bellazzini +24
The Gaia-ESO survey is a large public spectroscopic survey aimed at investigating the origin and formation history of our Galaxy by collecting spectroscopy of representative sample…
The Gaia-ESO Survey: the chemical structure of the Galactic discs from the first internal data release
Š. Mikolaitis, V. Hill, A. Recio-Blanco +31
Most high-resolution spectroscopic studies of the Galactic discs were mostly confined to objects in the solar vicinity. Here we aim at enlarging the volume in which individual chem…
