    • Extracting parameters from colour–magnitude diagrams 

      Bonatto, Charles Jose; Campos, Fabíola; Kepler, Souza Oliveira; Bica, Eduardo Luiz Damiani (2015) [Artigo de periódico]
      We present a simple approach for obtaining robust values of astrophysical parameters from the observed colour–magnitude diagrams (CMDs) of star clusters. The basic inputs are the Hess diagram built with the photometric ...

    • Near-infrared study of new embedded clusters in the Carina complex 

      Oliveira, Raphael Augusto Pereira de; Bica, Eduardo Luiz Damiani; Bonatto, Charles Jose (2018) [Artigo de periódico]
      We analyse the nature of a sample of stellar overdensities that we found projected on the Carina complex. This study is based on the Two Micron All Sky Survey photometry and involves the photometry decontamination of field ...

    • A pair of reddened young star clusters in Centaurus northern sample 

      Bica, Eduardo Luiz Damiani; Ortolani, Sergio; Momany, Yazan; Dutra, C. M.; Barbuy, Beatriz (2004) [Artigo de periódico]
      Photometry in the BVI and JHK bands is presented for the first time for the southern open clusters Danks 1 and 2, located in the Centaurus region. They are relatively rich and compact, and projected at approximately 4 ...

    • Segue 3 : the youngest globular cluster in the outer halo 

      Ortolani, Sergio; Bica, Eduardo Luiz Damiani; Barbuy, Beatriz (2013) [Artigo de periódico]
      Deep Galileo (Telescopio Nazionale Galileo) B, V and I images of Segue 3, reaching V ∼ 25, reveal that it is the youngest globular cluster known so far in the Galaxy.Ayoung age of 3.2 Gyr is found, differently from a ...
