• Blanketing effects in the very metal-rich bulge globular cluster terzan 1 

      Ortolani, Sergio; Bica, Eduardo Luiz Damiani; Barbuy, Beatriz (1993) [Artículo de periódico]
      We present BVRI and Gunn z CCD photometry for the bulge metal-rich globular cluster Terzan 1. The RGB shows an anomalous shape and the HB is extremely red. lt is projected on a very metal-rich bulge population. We demonstrate ...
    • Metallicity of the star III-17 in the bulge globular cluster NGC 6553 

      Barbuy, Beatriz; Castro, S.; Ortolani, Sergio; Bica, Eduardo Luiz Damiani (1992) [Artículo de periódico]
      CCD échelle spectra were obtained at the 3.6 m telescope at ESO for the star III-17 of the metal-rich globular cluster NGC 6553. This cluster was chosen because it is a relatively dose bulge globular cluster and also it ...
