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 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…
Direct N-body simulations of rotating and extremely massive Population III star clusters
Kai Wu, Ataru Tanikawa, Francesco Flammini Dotti +6
Aims. We present eight direct N-body simulations with NBODY6++GPU of extremely massive, initially rotating Population III star clusters with 1.01 x 10^5 stars. Methods. Our models…
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…
The effects of star-gas interactions on binary evolution in open clusters
Jixuan Yang, Lile Wang, Xinyu Li +3
Star-gas interactions can provide gravitational feedback that influences the dynamical evolution of stellar clusters, through processes such as dynamical friction (DF) and its non-…
The long-term evolution of Ultra Faint Dwarf Galaxies and observational implications
Francesco Flammini Dotti, Roberto Capuzzo-Dolcetta, Giovanni Carraro +2
Context. In the Local Group, dwarf spheroidal galaxies (dSphs) and ultra-faint dwarf galaxies (UFDs) exhibit large velocity dispersions. These values are generally attributed to th…
Intermediate Mass Black Hole Binary Evolution in Nuclear Star Clusters: the effect of the stellar mass black hole population
Fazeel Mahmood Khan, Peter Berczik, Margarita Sobolenko +4
In this study, we investigate the dynamics of Intermediate-Mass Black Hole (IMBH) binaries within Nuclear Star Clusters (NSCs) that contain a population of stellar-mass black holes…
Efficient black hole seed formation in low metallicity and dense stellar clusters with implications for JWST sources
M. C. Vergara, A. Askar, F. Flammini Dotti +7
Recent observations with the James Webb Space Telescope (JWST) reveal young massive clusters (YMCs) as key building blocks of early galaxies. They are not only important constituen…
Compact Binaries in Star Clusters II - Escapers and Detection Rates
J. M. B. Downing, M. J. Benacquista, M. Giersz +1
We use a self-consistent Monte Carlo treatment of stellar dynamics to investigate black hole binaries that are dynamically ejected from globular clusters to determine if they will…
