Chemical evolution of star clusters

open access: yes, 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 ...

Signatures of multiple stellar populations in unresolved extragalactic globular/ young massive star clusters [PDF]

open access: yes, 2013
We present an investigation of potential signatures of the formation of multiple stellar populations in recently formed extragalactic star clusters.

JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc

open access: yesThe 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.

THE SEQUENTIAL STAR FORMATION IN GLOBULAR CLUSTERS

open access: yesOdessa 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.

Hot stars in globular clusters [PDF]

open access: yes, 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.

Multiple populations in globular clusters. Lessons learned from the Milky Way globular clusters

open access: yes, 2012
Recent progress in studies of globular clusters has shown that they are not simple stellar populations, being rather made of multiple generations. Evidence stems both from photometry and spectroscopy.

Resolving Globular Cluster Formation within a Cosmological Context [PDF]

open access: yes, 2009
We place constraints on the formation redshifts for blue globular clusters (BGCs), independent of the details of hydrodynamics and population III star formation.

Star-Forming Galaxies at z~2 and the Formation of the Metal-Rich Globular Cluster Population

open access: yes, 2010
We examine whether the super star-forming clumps (R~1-3 kpc; M~10^8-10^9.5 Msun) now known to be a key component of star-forming galaxies at z~2 could be the formation sites of the locally observed old globular cluster population.
