    • 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) [Journal article]
      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 ...

    • Dynamical studies of cluster pairs in the magellanic clouds 

      Oliveira, Marcio Ramos de; Dottori, Horacio Alberto; Bica, Eduardo Luiz Damiani (1998) [Journal article]
      We performed N-body simulations of star cluster encounters with Hernquist’s TREECODE in a CRAY YMP-2E computer under different initial conditions (relative positions and velocities, cluster sizes, masses and concentration ...

    • Final stages of N-body star cluster encounters 

      Oliveira, Marcio Ramos de; Bica, Eduardo Luiz Damiani; Dottori, Horacio Alberto (2000) [Journal article]
      We performed numerical simulations of star cluster encounters with Hernquist's treecode on a CRAY YMP-2E computer. We used different initial conditions (relative positions and velocities, cluster sizes, masses and concentration ...

    • NGC 1912 and NGC 1907 : a close encounter between open clusters? 

      Oliveira, Marcio Ramos de; Fausti Neto, Angelo; Bica, Eduardo Luiz Damiani; Dottori, Horacio Alberto (2002) [Journal article]
      The possible physical relation between the closely projected open clusters NGC 1912 (M 38) and NGC 1907 is investigated. Previous studies suggested a physical pair based on similar distances, and the present study explores ...
