• Ages of the bulge globular clusters NGC 6522 and NGC 6626 (M28) from HST proper-motion-cleaned color–magnitude diagrams 

      Kerber, Leandro de Oliveira; Nardiello, Domenico; Ortolani, Sergio; Barbuy, Beatriz; Bica, Eduardo Luiz Damiani; Cassisi, Santi; Libralato, Mattia; Vieira, Rodrigo G. (2018) [Artigo de periódico]
      Bulge globular clusters (GCs) with metallicities [Fe/H]−1.0 and blue horizontal branches are candidates to harbor the oldest populations in the Galaxy. Based on the analysis of HST proper-motion-cleaned color–magnitude ...
    • A deep view of a fossil relic in the Galactic bulge : the Globular Cluster HP1 

      Kerber, Leandro de Oliveira; Libralato, Mattia; Souza, Stefano O.; Oliveira, Raphael Augusto Pereira de; Ortolani, Sergio; Pérez Villegas, Maria de Los Angeles; Barbuy, Beatriz; Dias, Bruno Moreira de Souza; Bica, Eduardo Luiz Damiani; Nardiello, Domenico (2019) [Artigo de periódico]
    • Halo intruders in the Galactic bulge revealed by HST and Gaia : the globular clusters Terzan 10 and Djorgovski 1 

      Ortolani, Sergio; Nardiello, Domenico; Pérez Villegas, Maria de Los Angeles; Bica, Eduardo Luiz Damiani; Barbuy, Beatriz (2019) [Artigo de periódico]
      Context. The low-latitude globular clusters Terzan 10 and Djorgovski 1 are projected in the Galactic bulge, in a Galactic region highly affected by extinction. A discrepancy of a factor of ∼2 exists in the literature in ...
    • Outliers : multicolour photometry guiding the search for evolved binary systems in the globular cluster 47Tucanae 

      Campos, Fabíola; Pelisoli, Ingrid Domingos; Kamann, Sebastian; Husser, Tim Oliver; Dreizler, Stefan; Bellini, Andrea; Robinson, E.L.; Nardiello, Domenico; Piotto, Giampaolo; Kepler, Souza Oliveira; Istrate, Alina G.; Winget, Donald Earl; Montgomery, Michael Houston; Dotter, Aaron Loveren (2018) [Artigo de periódico]
      We use Hubble Space Telescope multicolour photometry of the globular cluster 47 Tucanae to uncover a population of 24 objects with no previous classification that are outliers from the single-star model tracks in the ...
    • Photo-chemo-dynamical analysis and the origin of the bulge globular cluster Palomar 6 

      Souza, Stefano O.; Valentini, Marica; Barbuy, Beatriz; Pérez Villegas, Maria de Los Angeles; Chiappini, C.C.M.; Ortolani, Sergio; Nardiello, Domenico; Dias, Bruno Moreira de Souza; Anders, Friedrich; Bica, Eduardo Luiz Damiani (2021) [Artigo de periódico]
      Context. Palomar 6 (Pal6) is a moderately metal-poor globular cluster projected towards the Galactic bulge. A full analysis of the cluster can give hints on the early chemical enrichment of the Galaxy and a plausible origin ...
