Colour Magnitude Diagrams of the moderately metal-rich globular clusters NGC 6569 and Palomar 11.

ORTOLANI S., BICA E. and BARBUY B.

Abstract (from CDS):

For the first time Colour-Magnitude Diagrams are presented for NGC 6569 and Palomar 11. NGC 6569 is a rather concentrated cluster whereas Palomar 11 is loose and sparsely populated. Cluster parameters are derived from V and I photometry. These are red Horizontal Branch globular clusters, with metallicities comparable to that of 47 Tucanae. We derive a reddening E(B-V)≃0.53 and a distance from the Sun d☉≃9.8kpc for NGC 6569, and E(B-V)≃0.35 and d☉≃13.2kpc for Palomar 11. NGC 6569 is located in the bulge, while Palomar 11, despite its rather high metallicity, is in the inner halo, a rare case similar to that of 47 Tucanae.
