A family picture: tracing the dynamical path of the structural properties of multiple populations in globular clusters
E. Dalessandro, M. Cadelano, E. Vesperini +6
We studied the spatial distributions of multiple stellar populations (MPs) in a sample of 20 globular clusters (GCs) spanning a broad range of dynamical ages. The differences betwe…
Kinematical evolution of multiple stellar populations in star clusters
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
We present the results of a suite of \Nbody simulations aimed at understanding the fundamental aspects of the long-term evolution of the internal kinematics of multiple stellar pop…
Formation of Second Generation Stars in Globular Clusters
F. Calura, A. D'Ercole, E. Vesperini +2
By means of grid-based, 3D hydrodynamical simulations we study the formation of second generation (SG) stars in a young globular cluster (GC) of mass 10^7 Msun, the possible progen…
Discovery of a double Blue Straggler sequence in M15: new insight into the core-collapse process
Giacomo Beccari, Francesco R. Ferraro, Emanuele Dalessandro +8
In this paper we report on the discovery of a double blue straggler star (BSS) sequence in the core of the core-collapsed cluster M15 (NGC 7078). We performed a detailed photometri…
Astro2020 Science White Paper: Science at the edges: internal kinematics of globular clusters' external fields
A. Bellini, M. Libralato, J. Anderson +17
The outer regions of globular clusters can enable us to answer many fundamental questions concerning issues ranging from the formation and evolution of clusters and their multiple…
A panchromatic view of the bulge globular cluster NGC 6569
S. Saracino, E. Dalessandro, F. R. Ferraro +12
We used high-resolution optical HST/WFC3 and multi-conjugate adaptive optics assisted GEMINI GeMS/GSAOI observations in the near-infrared to investigate the physical properties of…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XVIII. Proper-motion kinematics of multiple stellar populations in the core regions of NGC 6352
M. Libralato, A. Bellini, G. Piotto +5
We present the analysis of the radial distributions and kinematic properties of the multiple stellar populations (mPOPs) hosted in the globular cluster (GC) NGC 6352 as part of the…
The Lithium test for multiple populations in Globular Clusters: Lithium in NGC 2808
Francesca D'Antona, Paolo Ventura, Anna Fabiola Marino +4
In the globular cluster NGC2808, a quasi-standard initial lithium abundance is derived for a red giant belonging to the `extreme' population, characterized by a large helium overab…
