The evolution of high-z proto-star clusters into local globular clusters
A. Della Croce, E. Vesperini, R. Pascale +4
The James Webb Space Telescope (JWST) detected numerous massive and relatively compact stellar clumps around proto-galaxies at high redshift (z>0.5). Their properties suggest that…
Massive star clusters detected by JWST as natural birth places to form intermediate-mass black holes
Dominik R. G. Schleicher, Matías Liempi, Mirek Giersz +11
The James Webb Space Telescope (JWST) has detected, through gravitational lensing, several young massive star clusters (YMCs), which are considered as relevant building blocks of h…
Distance Estimation and Sky Localization of Eccentric Double White Dwarf Binaries from Gravitational Wave Observations inside Globular Clusters
Yuetong Zhao, L. Hellström, Siqi Zhang +7
The cosmic distance scale is built on multiple different techniques for estimating distances in space that are often connected and dependent on multiple measurements and assumption…
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 massless particles in star clusters with NBODY6++GPU-MASSLESS: II. The long-term evolution of free-floating comets
Francesco Flammini Dotti, M. B. N. Kouwenhoven, Kai Wu +5
Context. Comets, asteroids, planetesimals, free-floating planets and brown dwarfs, are continuously injected into the intra-cluster environment after expulsion from their host plan…
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…
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…
Energy equipartition in multiple-population globular clusters
A. R. Livernois, F. I. Aros, E. Vesperini +7
We present the results of Monte Carlo simulations aimed at exploring the evolution towards energy equipartition of first- (1G) and second-generation (2G) stars in multiple-populati…
The Dragon-II simulations -- II. Formation mechanisms, mass, and spin of intermediate-mass black holes in star clusters with up to 1 million stars
Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem +4
The processes that govern the formation of intermediate-mass black holes (IMBHs) in dense stellar clusters are still unclear. Here, we discuss the role of stellar mergers, star-BH…
The Dragon-II simulations -- I. Evolution of single and binary compact objects in star clusters with up to 1 million stars
Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem +7
We present the first results of the \textsc{Dragon-II} simulations, a suite of 19 -body simulations of star clusters with up to stars, with up to of them initially…
MOCCA-SURVEY Database I: Dissolution of tidally filling star clusters harboring black hole subsystem
Mirek Giersz, Abbas Askar, Long Wang +3
We investigate the dissolution process of star clusters embedded in an external tidal field and harboring a subsystem of stellar-mass black hole. For this purpose we analyzed the M…
MOCCA Survey Database I: Dissolution of tidally filling star clusters harbouring BH subsystems
Mirek Giersz, Abbas Askar, Long Wang +3
We investigate the dissolution process for dynamically evolving star clusters embedded in an external tidal field by exploring the MOCCA Survey Database I, with focus on the presen…
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…
Compact Binaries in Star Clusters I - Black Hole Binaries Inside Globular Clusters
J. M. B. Downing, M. J. Benacquista, M. Giersz +1
We study the compact binary population in star clusters, focusing on binaries containing black holes, using a self-consistent Monte Carlo treatment of dynamics and full stellar evo…
Dynamics of Planetary Systems in Star Clusters
R. Spurzem, M. Giersz, D. C. Heggie +1
At least 10-15% of nearby sun-like stars have known Jupiter-mass planets. In contrast, very few planets are found in mature open and globular clusters such as the Hyades and 47 Tuc…
A stochastic Monte Carlo approach to model real star cluster evolution, II. Self-consistent models and primordial binaries
M. Giersz, R. Spurzem
The new approach outlined in Paper I (Spurzem \& Giersz 1996) to follow the individual formation and evolution of binaries in an evolving, equal point-mass star cluster is extended…
