Evolution of fractality in centrally concentrated young clusters

Almat Akhmetali, Adilkhan Assilkhan, Mordecai-Mark Mac Low +6

We investigate the structural evolution of young star clusters forming within centrally concentrated molecular clouds. Our simulations use the Torch framework, which integrates the…

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…

Searching for White Dwarf Candidates Formed Through Binary evolution in Star Clusters

Huahui Yan, Li Wang, David R. Miller +11

White dwarfs (WDs), the evolutionary endpoints of most stars, can form through both single-star and binary channels. While single-star evolutionary models enable reliable WD age es…

Rapid formation of a very massive star >50000 and subsequently an IMBH from runaway collisions. Direct N-body and Monte Carlo simulations of dense star clusters

Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah +15

Context. We present simulations of a massive young star cluster using \textsc{Nbody6++GPU} and \textsc{MOCCA}. The cluster is initially more compact than previously published model…

Evolution of star clusters with initial bulk rotation via N-body simulations

Abylay Bissekenov, Xiaoying Pang, Albrecht Kamlah +6

Young star clusters can inherit bulk rotation from the molecular clouds from which they have formed. This rotation can affect the long-term evolution of a star cluster and its cons…
