    • Dissolving star cluster candidates 

      Bica, Eduardo Luiz Damiani; Santiago, Basilio Xavier; Dutra, Carlos Maximiliano; Dottori, Horacio Alberto; Oliveira, Marcio Ramos de; Pavani, Daniela Borges (2001) [Artículo de periódico]
      We present a list of 34 neglected entries from star cluster catalogues located at relatively high galactic latitudes (|b| > 15º) which appear to be candidate late stages of star cluster dynamical evolution. Although ...

    • Open clusters or their remnants : B and V photometry of NGC 1901 and NGC 1252 

      Pavani, Daniela Borges; Bica, Eduardo Luiz Damiani; Dutra, Carlos Maximiliano; Dottori, Horacio Alberto; Santiago, Basilio Xavier; Carranza, Gustavo Jose; Díaz, Rubén Joaquín (2001) [Artículo de periódico]
      Photometry in the B and V bands is presented for the southern stellar groups NGC1901 and NGC1252. NGC1901 is often described as an open cluster while NGC 1252 consists of a concentration of about 20 stars centered ≈ 20' ...

    • The embedded star clusters in the nebulae NGC 2327 and BRC 27 in Canis Majoris R1 

      Soares, Jules Batista; Bica, Eduardo Luiz Damiani (2002) [Artículo de periódico]
      We employed J, H and Ks photometry from the 2MASS Catalogue to study the embedded star clusters in the nebulae NGC 2327 and BRC 27 locate in the molecular cloud Canis Majoris R1. We made use of colour-colour and colour-magnitudes ...
