Chemical evolution of star clusters
, 2009 I discuss the chemical evolution of star clusters, with emphasis on old globular clusters, in relation to their formation histories. Globular clusters clearly formed in a complex fashion, under markedly different conditions from any younger clusters ...

Globular cluster formation triggered by the initial starburst in galaxy formation [PDF]
, 1999 We propose and investigate a new formation mechanism for globular clusters in which they form within molecular clouds that are formed in the shocked regions created by galactic winds driven by successive supernova explosions shortly after the initial ...

Are there S stars in galactic globular clusters? [PDF]
Monthly Notices of the Royal Astronomical Society, 1984 Deux etoiles geantes rouges dans NGC 6723 montrent des bandes ZrO augmentees. Comparaisons avec les geantes de 47 Tuc et analogie avec les etoiles des Nuages de Magellan.

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.

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

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

Resolving Globular Cluster Formation within a Cosmological Context [PDF]
, 2009 We place constraints on the formation redshifts for blue globular clusters (BGCs), independent of the details of hydrodynamics and population III star formation.

Hot stars in globular clusters [PDF]
, 1995 Globular clusters are ideal laboratories to study the evolution of low-mass stars. In this review, I shall concentrate on two types of hot stars observed in globular clusters: horizontal branch stars and UV bright stars. The third type, the white dwarfs, are covered by Bono in this volume.

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.
