Searching for new observational signatures of the dynamical evolution of star clusters
B. Bhat, B. Lanzoni, F. R. Ferraro +1
We present a numerical study, based on Monte Carlo simulations, aimed at defining new empirical parameters measurable from observations and able to trace the different phases of st…
Evolution towards energy equipartition in star clusters: effects of the tidal field, primordial binaries, and internal velocity anisotropy
Václav Pavlík, Enrico Vesperini
This paper is the second in a series investigating the evolution of star clusters towards energy equipartition (EEP). Here, we focus on the effects of the external tidal field of t…
Early dynamics and violent relaxation of multi-mass rotating star clusters
A. R. Livernois, E. Vesperini, M. Tiongco +2
We present the results of a study aimed at exploring, by means of N-body simulations, the evolution of rotating multi-mass star clusters during the violent relaxation phase, in the…
3D core kinematics of NGC6362: central rotation in a dynamically evolved globular cluster
E. Dalessandro, S. Raso, S. Kamann +4
We present a detailed 3D kinematic analysis of the central regions () of the low-mass and dynamically evolved galactic globular cluster NGC 6362. The study is based on data…
A new identity card for the bulge globular cluster NGC 6440 from resolved star counts
Cristina Pallanca, Barbara Lanzoni, Francesco R. Ferraro +7
We present a new identity card for the cluster NGC 6440 in the Galactic Bulge. We have used a combination of high-resolution Hubble Space Telescope images, wide-field ground-based…
New insights into star cluster evolution towards energy equipartition
Václav Pavlík, Enrico Vesperini
We present the results of a study aimed at exploring the evolution towards energy equipartition in star cluster models with different initial degrees of anisotropy in the velocity…
Dynamical Evolution of Multiple-Population Globular Clusters
E. Vesperini, J. Hong, M. Giersz +1
We have carried out a set of Monte Carlo simulations to study a number of fundamental aspects of the dynamical evolution of multiple stellar populations in globular clusters with d…
First phase space portrait of a hierarchical stellar structure in the Milky Way
E. Dalessandro, A. L. Varri, M. Tiongco +10
We present the first detailed observational picture of a possible ongoing massive cluster hierarchical assembly in the Galactic disk as revealed by the analysis of the stellar full…
