Very metal-poor stars in the solar vicinity: kinematics and abundance analysis
Anastasiia Plotnikova, Giovanni Carraro, Sandro Villanova +1
Very metal-poor stars contain crucial information on the Milky Way's infancy. In our previous study \citep{Plotnikova_2022} we derived a mean age of 13.7 Gyr for a sample of…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XXIII. Proper-motion catalogs and internal kinematics
M. Libralato, A. Bellini, E. Vesperini +17
A number of studies based on data collected by the () GO-13297 program "HST Legacy Survey of Galactic Globular Clusters: Shedding UV…
Photo-chemo-dynamical analysis and the origin of the bulge globular cluster Palomar 6
Stefano O. Souza, Marica Valentini, Beatriz Barbuy +7
Palomar 6 (Pal~6) is a moderately metal-poor globular cluster projected towards the Galactic bulge. A full analysis of the cluster can give hints on the early chemical enrichment o…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XX. Ages of single and multiple stellar populations in seven bulge globular clusters
R. A. P. Oliveira, S. O. Souza, L. O. Kerber +23
In the present work we analyzed seven globular clusters selected from their location in the Galactic bulge and with metallicity values in the range $-1.30\lesssim\rm{[Fe/H]}\lesssi…
Globular clusters in the inner Galaxy classified from dynamical orbital criteria
Angeles Pérez-Villegas, Beatriz Barbuy, Leandro Kerber +3
Globular clusters (GCs) are the most ancient stellar systems in the Milky Way. Therefore, they play a key role in the understanding of the early chemical and dynamical evolution of…
Orbits of selected globular clusters in the Galactic bulge
A. Pérez-Villegas, L. Rossi, S. Ortolani +3
We present orbit analysis for a sample of 8 inner bulge globular clusters, together with one reference halo object. We used proper motion values derived from long time base CCD dat…
