Abstract:
We present the first results of a detailed abundance analysis, based on VLT observations, of giant stars in the very metal-rich globular cluster NGC 6528. We will be able to tie the horizontal branch abundances (see e.g. Carretta et al. 2001) to those of the more luminous giants (see CMDs). For the very similar cluster NGC 6553 studies of different types of stars have yielded very disparate results. Our first analysis of three of our stars seem to indicate that indeed the different sorts of stars do show similar abundances if one homogeneous set of models and parameters are being used.
