Dynamical Formation of Cataclysmic Variables in Globular Clusters
Jongsuk Hong, Enrico Vesperini, Diogo Belloni +1
The formation and evolution of X-ray sources in globular clusters is likely to be affected by the cluster internal dynamics and the stellar interactions in the cluster dense enviro…
Investigating mass segregation process in globular clusters with Blue Straggler Stars: the impact of dark remnants
Emiliano Alessandrini, Barbara Lanzoni, Francesco Rosario Ferraro +2
We present the results of a set of N-body simulations aimed at exploring how the process of mass segregation (as traced by the spatial distribution of blue straggler stars, BSSs) i…
On the Link Between Energy Equipartition and Radial Variation in the Stellar Mass Function of Star Clusters
Jeremy J. Webb, Enrico Vesperini
We make use of -body simulations to determine the relationship between two observable parameters that are used to quantify mass segregation and energy equipartition in star clus…
Radial Variation in the Stellar Mass Functions of Star Clusters
Jeremy J. Webb, Enrico Vesperini
A number of recent observational studies of Galactic globular clusters have measured the variation in the slope of a cluster's stellar mass function with clustercentric distanc…
Accretion of pristine gas and dilution during the formation of multiple-population globular clusters
A. D'Ercole, F. D'Antona, E. Vesperini
We study the interaction of the early spherical GC wind powered by Type II supernovae (SNe II) with the surrounding ambient medium consisting of the gaseous disk of a star forming…
Kinematical evolution of tidally limited star clusters: the role of retrograde stellar orbits
Maria Tiongco, Enrico Vesperini, Anna Lisa Varri
The presence of an external tidal field often induces significant dynamical evolutionary effects on the internal kinematics of star clusters. Previous studies investigating the res…
Evolution of Binary Stars in Multiple-Population Globular Clusters - II. Compact Binaries
Jongsuk Hong, Enrico Vesperini, Antonio Sollima +3
We present the results of a survey of N-body simulations aimed at exploring the evolution of compact binaries in multiple-population globular clusters.We show that as a consequence…
A unique model for the variety of multiple populations formation(s) in globular clusters: a temporal sequence
F. D'Antona, E. Vesperini, A. D'Ercole +4
We explain the multiple populations recently found in the 'prototype' Globular Cluster (GC) NGC 2808 in the framework of the asymptotic giant branch (AGB) scenario. The chemistry o…
