Centrally concentrated star formation in young clusters II: Jet feedback
Adilkhan Assilkhan, Sabrina M. Appel, Bekdaulet Shukirgaliyev +5
Protostellar jets are one of the earliest forms of stellar feedback, but their impact on star formation and cluster assembly in centrally concentrated molecular clouds remains poor…
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…
The contribution to Galactic Centre γ-ray excess from cluster-born millisecond pulsars. Constraints from direct N-body simulations
M. Kalambay, M. Ishchenko, D. Kuvatova +2
The Galactic Centre γ-ray excess (GCE), observed by Fermi-LAT around Sgr A*, exceeds expectations from standard cosmic-ray models and is commonly attributed either to dark matter a…
Centrally concentrated star formation in young clusters
Adilkhan Assilkhan, Mordecai-Mark Mac Low, Brooke Polak +6
The study of star cluster evolution necessitates modeling how their density profiles develop from their natal gas distribution. Observational evidence indicates that many star clus…
Cluster membership analysis with supervised learning and -body simulations
A. Bissekenov, M. Kalambay, E. Abdikamalov +3
Membership analysis is an important tool for studying star clusters. There are various approaches to membership determination, including supervised and unsupervised machine learnin…
Dynamical evolution of Milky Way globular clusters on the cosmological timescale I. Mass loss and interaction with the nuclear star cluster
M. Ishchenko, P. Berczik, T. Panamarev +7
Context. Based on the Gaia DR3, we reconstructed the orbital evolution of the known Milky Way globular clusters and found that six objects, NGC 6681, NGC 6981, Palomar 6, NGC 6642,…
Fractal dimension of star clusters
N. Ussipov, A. Akhmetali, M. Zaidyn +4
Quantitative analysis of the structure of star clusters is crucial for understanding their formation and evolution. In this article, we explore the application of fractal dimension…
Milky Way globular clusters on cosmological timescales. III. Interaction rates
Maryna Ishchenko, Margaryta Sobolenko, Peter Berczik +4
Aims. We carry out the self-consistent dynamic evolution of the orbital structure of Milky Way globular clusters. This allows us to estimate possible and probable close passages an…
Evolution of open clusters with or without black holes
B. Shukirgaliyev, P. Berczik, A. Otebay +6
Binary black holes (BHs) can be formed dynamically in the centers of star clusters. The high natal kicks for stellar-mass BHs used in previous works made it hard to retain BHs in s…
Milky Way Globular Clusters: close encounter rates with each other and with the Central Supermassive Black Hole
Maryna V. Ishchenko, Margarita O. Sobolenko, Mukhagali T. Kalambay +2
Using the data from Gaia (ESA) Data Release 2 we performed the orbital calculations of globular clusters (GCs) of the Milky Way. To explore possible collisions between the GCs, usi…
The bound mass of Dehnen models with centrally peaked star formation efficiency
B. Shukirgaliyev, A. Otebay, M. Sobolenko +12
Understanding the formation of star clusters with low star-formation efficiency (SFE) is very important to know about the star-formation history. In N-body models of star cluster e…
