CCD photometry of the old clusters ESO 093-SC08 and Van den Bergh-Hagen 176.

PHELPS R.L. and SCHICK M.

Abstract (from CDS):

Faint-magnitude CCD photometry has been obtained for the clusters ESO 093-SC08 and van den Bergh-Hagen 176. These data reveal ESO 093-SC08 to be an old open cluster, with a derived age of 5.5±1.0 Gyr, a heliocentric distance of 14.00±0.75 kpc, an inferred metallicity in the range -0.60≤[Fe/H]≤-0.20 dex, and Galactocentric positions RGC=13.0±0.7 kpc and Z=-1000±50 pc. For van den Bergh-Hagen 176, a derived age of 7.0±1.5 Gyr, a heliocentric distance of 18.00±1.00 kpc, an inferred metallicity in the range -0.20≤[Fe/H]≤0.20 dex, and Galactocentric positions RGC=12.0±0.9 kpc and Z=+1350±100 pc are found. The current results for ESO 093-SC08 are in good agreement with a study by Bica et al. Van den Bergh-Hagen 176 appears to be a massive metal-rich old cluster, similar to NGC 6791, or a young, metal-rich globular cluster.
