Integrated spectral study of reddened globular clusters and candidates.

Abstract (from CDS):

This paper presents integrated spectra in the range 6700-9500Å for 20 Galactic globular clusters (and candidates) in the bulge and 5 others projected on the Galactic disk (|l|>30° and |b|<5°). Most of them are considerably reddened and are among those least studied in the literature. We derive reddening and metallicity from flux-calibrated spectra, thus providing independent information of that derived through colour-magnitude studies. For some clusters in the sample, these parameters have been determined for the first time, and for others a considerable revision is given. We indicate the globular clusters which definitely belong to the bulge metal-rich and intermediate metallicity families. Among the objects projected on the disk, we find that the integrated spectral properties of Lyngå 7, BH 176 and Palomar 10 are compatible with those of metal-rich globular clusters. Finally, ESO93-SC08 is an old open cluster, and UKS2 is an open cluster with age ≃1Gyr.
