Poster Title: The metal rich stellar populations in Omega Centauri
Abstract: Authors: E. Pancino, F.R.Ferraro, M.Bellazzini, L.Origlia, V.Hill, L. Pasquini
After the recent discovery of a metal-rich, presumably younger, stellar component (the RGB-a) in the globular cluster omega Centauri, we have started a coordinated spectro-photometric project devoted to the complete characterization of this anomaous sub-population. Some of the most recent results concerning the RGB-a are presented, along with some additional side-projects connected with the study of the other sub-populations in omega Centauri.
