Horizontal Branch Stars

The chemical composition of 11 suspected RHB stars in the galactic field was recently analyzed using high-resolution spectra obtained with the 6-meter telescope of the Special Astrophysical Observatory, North Caucasus. We summarize here some of the main conclusions obtained from comparison of the abundances of the RHB stars with available abundances of giants and dwarfs (hereafter G and D).

AbstractOptical/near-infrared observations of 14 globular cluster (GC) systems in early-type galaxies are presented. We investigate the recent claims (Yoon et al. 2006) of colour bimodality in GC systems being an artefact of the nonlinear colour–metallicity transformation driven by horizontal-branch morphology. Taking advantage of the fact that the combination of optical and near-infrared colours can, in principle, break the age/metallicity degeneracy we also analyse age distributions in these systems.
