The internal kinematics and chemistry of 20 Milky Way strings
C. Boeche, A. Vallenari, J. Alonso-Santiago +8
Context: the recent discovery of filamentary stellar structures in the Milky Way disk raises the question of their formation in the context of the Galaxy evolution. Aims: in this w…
On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
Neutron-Capture Element Signatures in Globular Clusters: Insights from the Gaia-ESO Survey
J. Schiappacasse-Ulloa, L. Magrini, S. Lucatello +8
Globular clusters (GCs) are key to understanding the formation and evolution of our Galaxy. While the abundances of light and Fe-peak elements in GCs have been widely studied, inve…
Heavy element abundances in Galactic Globular Clusters
J. Schiappacasse-Ulloa, S. Lucatello, G. Cescutti +1
Context. Globular clusters are considered key objects for understanding the formation and evolution of the Milky Way. In this sense, their characterisation in terms of their chemic…
High-resolution spectroscopy of the young open cluster M 39 (NGC 7092)
J. Alonso-Santiago, A. Frasca, G. Catanzaro +5
M 39 is a nearby young open cluster hardly studied in the last decades. No giant is known among its members and its chemical composition has never been studied. In order to investi…
Terzan 8: a Sagittarius-flavoured globular cluster
Eugenio Carretta, Angela Bragaglia, Raffaele G. Gratton +3
Massive globular clusters (GCs) contain at least two generations of stars with slightly different ages and clearly distinct light elements abundances. The Na-O anticorrelation is t…
