description: The thesis work presented here concentrates mostly on the definition and the study of the recently discovered (Lee et al., 1999; Pancino et al., 2000) metal-rich population in ω Cen, since its exact nature is still very poorly known. The work includes: wide-field optical photometry to study the properties, spatial distribution and morphology of the multiple populations; high-resolution spectroscopy to characterize its chemistry and possible origin and evolution; and proper motion studies to characterize it kinematically. As a result, the metal-rich population appears different from the other sub-populations in all the above respects.
