Primordial Binary Stars, Mass segregation and Fractality Effects on the Early Evolution of Young Open Clusters
Vahid Amiri, Francesco Flammini Dotti, Xiaoying Pang +4
We want to understand how the combined effect of initial substructure, primordial mass segregation, and primordial binaries affects the dynamical evolution of the cluster, and whic…
Formation of a nuclear star cluster through the inspiral of globular clusters: A case study of the dwarf elliptical galaxy UGC 7346
Ismael Khan, Fazeel Mahmood Khan, Andrea V. Macciò +2
Nuclear star clusters (NSCs) are dense stellar environments located in the center of most galaxies. NSCs are thought to form through two primary methods; through the inspiral of gl…
Is the overconcentration of pristine populations in Galactic globular clusters real? An N-body approach to the problem
P. Berczik, O. Sobodar, F. Flammini Dotti +5
Recent observations indicate that in some Milky Way globular clusters (GCs) pristine red giant branch (RGB) stars appear more centrally concentrated than enriched ones. This contra…
Dynamical evolution of Milky Way globular clusters on the cosmological timescale II. Terzan 2, 4, and 5 mass loss and collision tracking
M. Ishchenko, P. Berczik, D. Kuvatova
We investigate the long-term dynamical evolution of Ter2, Ter4, and Ter5, focusing on their mutual interactions, mass-loss behaviour, and survivability in the dense Galactic centre…
Formation and disruption of wide binaries in star clusters revealed by N-body simulations
Abylay Bissekenov, Xiaoying Pang, Rainer Spurzem +3
Wide (soft) binaries are expected to be rapidly disrupted in dense stellar environments, yet they are observed in both the Galactic field and open clusters (OCs). In this paper, we…
Global m=1 slow mode in near-Keplerian self-gravitating torus: applications to stellar nuclear disks and AGN molecular tori
Elena Bannikova, Volodymyr Akhmetov, Peter Berczik +3
Global m=1 asymmetries are observed in many self-gravitating astrophysical systems and are often interpreted as large-scale slow modes in near-Keplerian potentials. Prominent examp…
