NTT V, I and Gunn z colour-magnitude diagrams of Liller 1: a globular cluster as metal-rich as the inner bulge stellar population ? Ortolani S., Bica E., Barbuy B. <Astron. Astrophys. 306, 134 (1996)> =1996A&A...306..134O (SIMBAD/NED BibCode)
ADC_Keywords:Clusters, globular ; Photometry, VRI; Keywords: Galaxy: globular clusters: individual: Liller 1 - stars: HR diagram - stars: abundances Description: We carried out VRI and Gunn z observations of the obscured globular cluster Liller 1. The cluster is so reddened (AV≃9.0) that it is at the detection limit in V. The RGB in I vs. (I-z) shows a strong curvature. Recalling that the nearly solar metallicity globular clusters NGC 6553 and NGC 6528 present similar blanketing effects only in the visible bandpasses, we conclude that Liller 1 is considerably more metal-rich than these clusters. The CMD comparison of Liller 1 with the inner bulge field around it (located ≃5deg from the nucleus), suggests that the cluster is as metallic as the most metallic fraction of this inner bulge population. Similarly deep I and z observations at ≃0.5deg away from Liller 1, at the nominal position of Grindlay 1 do not reveal any cluster.
