Stellar-mass black holes in young massive and open stellar clusters -- VII. Comparisons with gravitational-wave events until LVK-O4a and Gaia compact binaries

Sambaran Banerjee

Gravitational-wave (GW) detections by the LIGO-Virgo-KAGRA (LVK) observatories suggest multiple formation channels for GW compact binary mergers. Here I assess the role of young ma…

The velocity dispersion profile of nine open clusters in the solar neighborhood

Bingqian Ma, XiaoYing Pang, Sambaran Banerjee +2

We analyze the velocity dispersion profiles of nine open clusters in the solar neighborhood using kinematic data from Gaia DR 3, aiming to identify potential dynamical signatures o…

Stellar-mass black holes in young massive and open stellar clusters -- VI. Role of external galactic field

Sambaran Banerjee

Young massive clusters (YMC) and open clusters (OC) are widely considered as potential environments for assembling merging binary stellar-remnant black holes (BBH) via dynamical in…

Black hole mergers in compact star clusters and massive black hole formation beyond the mass-gap

Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem +4

We present direct N-body simulations, carried out with Nbody6++GPU, of young and compact low metallicity star clusters with stars, a velocity dispersion of …

Demographics of neutron stars in young massive and open clusters

Giacomo Fragione, Sambaran Banerjee

Star clusters appear to be the ideal environment for the assembly of neutron star-neutron star (NS-NS) and black hole-neutron star (BH-NS) binaries. These binaries are among the mo…

Neutron stars and millisecond pulsars in star clusters: implications for the diffuse -radiation from the Galactic Centre

Giacomo Fragione, Václav Pavlík, Sambaran Banerjee

Globular clusters (GCs) are the ideal environment for the formation of neutron stars (NSs) and millisecond pulsars (MSPs). NSs origin and evolution provide a useful information on…

The bound fraction of young star clusters

N. Brinkmann, S. Banerjee, B. Motwani +1

The residual gas within newly formed star clusters is expelled through stellar feedback on timescales ~ 1 Myr. The subsequent expansion of the cluster results in an unbinding of a…

Blue straggler formation at core collapse

Sambaran Banerjee

Among the most striking feature of blue straggler stars (BSS) is the presence of multiple sequences of BSSs in the colour-magnitude diagrams (CMDs) of several globular clusters. It…

Formation of Very Young Massive Clusters and implications for globular clusters

Sambaran Banerjee, Pavel Kroupa

How Very Young Massive star Clusters (VYMCs; also known as "starburst" clusters), which typically are of and are a few Myr old, form out of Giant Molecular Cl…

Initial conditions of formation of starburst clusters: constraints from stellar dynamics

Sambaran Banerjee

How starburst clusters form out of molecular clouds is still an open question. In this article, I highlight some of the key constraints in this regard, that one can get from the dy…

How can young massive clusters reach their present-day sizes?

Sambaran Banerjee, Pavel Kroupa

The classic question that how young massive star clusters attain their shapes and sizes, as we find them today, remains to be a challenge. Both observational and computational stud…

Possible smoking-gun evidence for initial mass segregation in re-virialized post-gas expulsion globular clusters

Hosein Haghi, Akram Hasani Zonoozi, Pavel Kroupa +2

We perform a series of direct -body calculations to investigate the effect of residual gas expulsion from the gas-embedded progenitors of present-day globular clusters (GCs) on…

The formation of NGC 3603 young starburst cluster: "prompt" hierarchical assembly or monolithic starburst?

Sambaran Banerjee, Pavel Kroupa

The formation of very young massive clusters or "starburst" clusters is currently one of the most widely debated topic in astronomy. The classical notion dictates that a star clust…

A perfect starburst cluster made in one go: the NGC 3603 young cluster

Sambaran Banerjee, Pavel Kroupa

Understanding how distinct, near-spherical gas-free clusters of very young, massive stars shape out of vast, complex clouds of molecular hydrogen is one of the biggest challenges i…

R144 : a very massive binary likely ejected from R136 through a binary-binary encounter

Seungkyung Oh, Pavel Kroupa, Sambaran Banerjee

R144 is a recently confirmed very massive, spectroscopic binary which appears isolated from the core of the massive young star cluster R136. The dynamical ejection hypothesis as an…

Did the infant R136 and NGC 3603 clusters undergo residual gas expulsion?

Sambaran Banerjee, Pavel Kroupa

Based on kinematic data observed for very young, massive clusters that appear to be in dynamical equilibrium, it has recently been argued that such young systems set examples where…

On the true shape of the upper end of the stellar initial mass function: The case of R136

Sambaran Banerjee, Pavel Kroupa

Context: The shape of the stellar initial mass function (IMF) of a star cluster near its upper mass limit is a focal topic of investigation as it determines the high mass stellar c…

Runaway massive stars from R136: VFTS 682 is very likely a "slow runaway"

Sambaran Banerjee, Pavel Kroupa, Seungkyung Oh

We conduct a theoretical study on the ejection of runaway massive stars from R136 --- the central massive, star-burst cluster in the 30 Doradus complex of the Large Magellanic Clou…
