    • The metal content of the bulge globular cluster NGC 6528 

      Zoccali, Manuela; Barbuy, Beatriz; Hill, Vanessa; Ortolani, Sergio; Renzini, Alvio; Bica, Eduardo Luiz Damiani; Momany, Yazan; Pasquini, Luca; Minniti, Dante; Rich, Robert Michael (2004) [Artículo de periódico]
      High resolution spectra of five stars in the bulge globular cluster NGC 6528 were obtained at the 8m VLT UT2-Kueyen telescope with the UVES spectrograph. Out of the five stars, two of them showed evidence of binarity. The ...

    • VLT-UVES abundance analysis of four giants in NGC 6553 

      Alves-Brito, Alan; Barbuy, Beatriz; Zoccali, Manuela; Minniti, Dante; Ortolani, Sergio; Hill, Vanessa; Renzini, Alvio; Pasquini, Luca; Bica, Eduardo Luiz Damiani; Rich, Robert Michael; Meléndez, Jorge; Momany, Yazan (2006) [Artículo de periódico]
      Context. Metal-rich globular clusters trace the formation of bulges. Abundance ratios in the metal-rich globular clusters such as NGC 6553 can constrain the formation timescale of the Galactic bulge. Aims. The purpose of ...

    • VLT-UVES analysis of 5 giants in 47 Tucanae 

      Alves-Brito, Alan; Barbuy, Beatriz; Ortolani, Sergio; Momany, Yazan; Hill, Vanessa; Zoccali, Manuela; Renzini, Alvio; Minniti, Dante; Pasquini, Luca; Bica, Eduardo Luiz Damiani; Rich, Robert Michael (2005) [Artículo de periódico]
      High resolution spectra of 5 giants, including a horizontal branch star, of the metal-rich globular cluster 47 Tucanae were obtained with the UVES spectrograph at the 8m VLT UT2-Kueyen telescope. The atmospheric parameters ...

    • VLT-UVES analysis of two giants in the bulge metal-poor globular cluster HP-1 

      Barbuy, Beatriz; Zoccali, Manuela; Ortolani, Sergio; Momany, Yazan; Hill, Vanessa; Yadav, Ramakant Singh; Renzini, Alvio; Minniti, Dante; Pasquini, Luca; Bica, Eduardo Luiz Damiani; Rich, Robert Michael (2006) [Artículo de periódico]
      Context. Metal-poor globular clusters in the bulge are important tracers of early chemical evolution. HP-1 is among the six metal-poor clusters within 5. of the Galactic center, and could be the one closest to the center ...

    • VLT-UVES spectroscopy of a bulge giant magnified through microlensing : EROS-BLG-2000-5 

      Minniti, Dante; Barbuy, Beatriz; Hill, Vanessa; Bica, Eduardo Luiz Damiani; Ortolani, Sergio; Rich, Robert Michael; Cook, Kern H.; Vandehei, Thor; Renzini, Alvio; Pasquini, Luca; Bennett, David P. (2002) [Artículo de periódico]
      High resolution spectra of a magnified bulge star were obtained at the 8 m Kueyen VLT-UT2 telescope with the UVES spectrograph. The source is a bulge giant of baseline magnitude VEROS = 18.4, magnified to V ≈ 18.0. These ...
