    • Characterization of open clusters remnants 

      Pavani, Daniela Borges; Bica, Eduardo Luiz Damiani (2007) [Artigo de periódico]
      Context. Despite progress in the theoretical knowledge of open cluster remnants and the growing search for observational identifications in recent years, open questions still remain. The methods used to analyze open cluster ...

    • Diagnostic tool to analyse colour–magnitude diagrams of poorly populated stellar concentrations 

      Pavani, Daniela Borges; Kerber, Leandro de Oliveira; Bica, Eduardo Luiz Damiani; Maciel, Walter Junqueira (2011) [Artigo de periódico]
      The dynamical processes that lead to open cluster disruption cause its mass to decrease. To investigate such processes from the observational point of view, it is important to identify open cluster remnants (OCRs), which ...

    • 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) [Artigo 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 ...

    • A multi-band catalog of 10978 star clusters, associations, and candidates in the Milky Way 

      Bica, Eduardo Luiz Damiani; Pavani, Daniela Borges; Bonatto, Charles Jose; Lima, Eliade Ferreira (2019) [Artigo de periódico]
      We present a catalog of Galactic star clusters, associations and candidates with 10978 entries. This multi-band catalog was constructed over 20 years, starting with visual inspections on the Digital Sky Survey and incremented ...

    • NGC 2180 : a disrupting open cluster? 

      Bonatto, Charles Jose; Bica, Eduardo Luiz Damiani; Pavani, Daniela Borges (2004) [Artigo de periódico]
      The spatial dependence of luminosity and mass functions of evolved open clusters is discussed in this work using J and H 2MASS photometry, which allows a wide spatial coverage and proper background determination. The target ...

    • 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) [Artigo 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' ...

    • Ruprecht 3 : an old star cluster remnant? 

      Pavani, Daniela Borges; Bica, Eduardo Luiz Damiani; Ahumada, Andrea Veronica; Claria Olmedo, Juan Jose (2003) [Artigo de periódico]
      2MASS J and H photometry and integrated spectroscopy are employed to study the nature of the poorly populated compact concentration of stars Ruprecht 3, which was previously catalogued as an open cluster. The integrated ...

    • The relationship between the Sérsic law profiles measured along the major and minor axes of elliptical galaxies 

      Ferrari, Fabricio; Dottori, Horacio Alberto; Caon, Nicola; Nóbrega, Antonio José Farias; Pavani, Daniela Borges (2004) [Artigo de periódico]
      In this paper we discuss the reason why the parameters of the Sérsic model best-fitting the major axis light profile of elliptical galaxies can differ significantly from those derived for the minor axis profile.We show ...

    • Utilizando a câmera fotográfica digital como ferramenta para distinguir as cores das estrelas 

      Marranghello, Guilherme Frederico; Pavani, Daniela Borges (2011) [Artigo de periódico]
