Ntt v, i, and gunn z colour-magnitude diagrams of liller 1 : a globular cluster as metal-rich as the inner bulge stellar population?
(1996) [Artigo de periódico]We carried out V RI 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 ... -
Synthesis of the integrated spectrum of metal-rich globular clusters using the hr diagram and a stellar library
(1995) [Artigo de periódico]An average integrated spectrum of the nearlysolar metallicity globular clusters NGC 6528, NGC 6553 and NGC 6440 is synthesized in the range 3500 < λ < 9750Å with a library of stellar spectra and constraints provided by the ...
