Spatial mixing of binary stars in multiple-population globular clusters
Jongsuk Hong, Saahil Patel, Enrico Vesperini +2
We present the results of a study aimed at investigating the effects of dynamical evolution on the spatial distribution and mixing of primordial binary stars in multiple-population…
The unexpected kinematics of multiple populations in NGC6362: do binaries play a role?
E. Dalessandro, A. Mucciarelli, M. Bellazzini +9
We present a detailed analysis of the kinematic properties of the multiple populations (MPs) in the low-mass Galactic globular cluster NGC6362 based on a sample of about 500 member…
The Structural and Kinematic Evolution of Central Star Clusters in Dwarf Galaxies and Their Dependence on Dark Matter Halo Profiles
Jeremy J. Webb, Enrico Vesperini
Through a suite of direct N-body simulations, we explore how the structural and kinematic evolution of a star cluster located at the center of a dwarf galaxy is affected by the sha…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - XV. The dynamical clock: reading cluster dynamical evolution from the segregation level of blue straggler stars
F. R. Ferraro, B. Lanzoni, S. Raso +17
The parameter A+, defined as the area enclosed between the cumulative radial distribution of blue straggler stars (BSSs) and that of a reference population, is a powerful indicator…
The strong rotation of M5 (NGC 5904) as seen from the MIKiS Survey of Galactic Globular Clusters
B. Lanzoni, F. R. Ferraro, A. Mucciarelli +10
In the context of the ESO-VLT Multi-Instrument Kinematic Survey (MIKiS) of Galactic globular clusters, we present the line-of-sight rotation curve and velocity dispersion profile o…
MIKiS: the Multi-Instrument Kinematic Survey of Galactic Globular Clusters. I. Velocity dispersion profiles and rotation signals of 11 globular clusters
F. R. Ferraro, A. Mucciarelli, B. Lanzoni +11
We present the first results of the Multi-Instrument Kinematic Survey of Galactic Globular Clusters, a project aimed at exploring the internal kinematics of a representative sample…
Evolution of the Stellar Mass Function in Multiple-Population Globular Clusters
Enrico Vesperini, Jongsuk Hong, Jeremy J. Webb +2
We present the results of a survey of N-body simulations aimed at studying the effects of the long-term dynamical evolution on the stellar mass function (MF) of multiple stellar po…
The complex kinematics of rotating star clusters in a tidal field
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
We broaden the investigation of the dynamical properties of tidally perturbed, rotating star clusters by relaxing the traditional assumptions of coplanarity, alignment, and synchro…
