Abstract

Globular clusters are tracers of the Galaxy formation, and their properties inform about their own formation and stellar populations. In this study we select clusters that have a metallicity Fe/H~-1.0, and preferentially in the Galactic bulge. The data were obtained within the project GO-13297, with principal investigator PI: Giampaolo Piotto, where images of clusters were taken in the UV filters 275W, F336W and F438W, onboard the Hubble Space Telescope (HST). The aim is to obtain conclusions on multiple stellar populations, and their stellar evolution, their ages and helium content, and the chemical evolution of the Galaxy at early times. (AU)
