The Disruption of Globular Star Clusters in the Galaxy: A Comparative Analysisbetween Fokker-Planck and N-Body Models [PDF]
, 1998 Recent N-body simulations have shown that there is a serious discrepancy between the results of the N-body simulations and the results of Fokker-Planck simulations for the evolution of globular and rich open clusters under the influence of the galactic ...

r-process Abundance Patterns in the Globular Cluster M92
The Astrophysical Journal, 2023 Whereas light-element abundance variations are a hallmark of globular clusters, there is little evidence for variations in neutron-capture elements. A significant exception is M15, which shows a star-to-star dispersion in neutron-capture abundances of at

Dark Matter Effects on Stellar Populations in Globular Clusters [PDF]
arXiv, 2021 According to the classical view of globular clusters, stars inside globular clusters are evolved from the same giant molecular cloud. Then their stars' chemical compositions must be the same. But recent photometric and spectroscopic studies of globular clusters reveal the presence of more-than-one stellar populations inside globular clusters.

JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc
The Astrophysical Journal, 2023 Star cluster formation in the early universe and its contribution to reionization remains largely unconstrained to date. Here we present JWST/NIRCam imaging of the most highly magnified galaxy known at z ∼ 6, the Sunrise arc.

Globular clusters as the relics of regular star formation in ‘normal’ high-redshift galaxies [PDF]
, 2015 We present an end-to-end, two-phase model for the origin of globular clusters (GCs). In the model, populations of stellar clusters form in the high-pressure discs of high-redshift ($z>2$) galaxies (a rapid-disruption phase due to tidal perturbations from

The ESO-VLT MIKiS Survey Reloaded: Exploring the Internal Kinematics of NGC 6440
The Astrophysical Journal, 2023 In the context of the ESO-VLT Multi-Instrument Kinematic Survey of Galactic globular clusters, here we present the line-of-sight velocity dispersion profile of NGC 6440, a massive globular cluster located in the Galactic bulge.

THE SEQUENTIAL STAR FORMATION IN GLOBULAR CLUSTERS
Odessa Astronomical Publications, 2008 The results of [O/Na] abundance modelling in globular clusters NGC 2808 and NGC 6752 are presented. The evolutionary scenario allowing to reproduce characteristic observed features of [O/Na] distribution function has been suggested.

Globular Cluster Formation [PDF]
, 2002 The discovery of young globular clusters in merging galaxies and other environments provides an opportunity to study directly the process of globular cluster formation. Empirically it appears that globular cluster formation occurs preferentially in regions in which star formation occurs at a high rate and efficiency. Further, the interstellar medium in

Black holes: The next generation—repeated mergers in dense star clusters and their gravitational-wave properties [PDF]
Physical Review D, 2019 When two black holes merge in a dense star cluster, they form a new black hole with a well-defined mass and spin. If that "second-generation" black hole remains in the cluster, it will continue to participate in dynamical encounters, form binaries, and ...
