    • Spectroscopic search for binaries among EHB stars in globular clusters 
      Bidin, C. Moni; Méndez Bussard, René Alejandro; Moehler, S.; Piotto, G.; Recio Blanco, A.; Momany, Y. (INST THEORETICAL PHYSICS ASTRONOMY, 2006)
      We performed a spectroscopic search for binaries among hot horizontal branch stars in globular clusters. We present final results for a sample of 51 stars in NGC 6752 and preliminary results for the first 15 stars analyzed ...
    • VLT-UVES abundance analysis of four giants in NGC 6553 
      Alves Brito, A.; Barbuy, B.; Zoccali, Manuela; Minniti, D.; Ortolani, S.; Hill, V.; Renzini, A.; Pasquini, L.; Bica, E.; Rich, R. M.; Meléndez, J.; Momany, Y. (EDP SCIENCES S A, 2006-12)
      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 ...
