      Context. VISTA Variables in the Vía Láctea (VVV) is one of the six ESO Public Surveys operating on the new 4-m Visible and Infrared Survey Telescope for Astronomy (VISTA). VVV is scanning the Milky Way bulge and an adjacent ...

    • A survey of early-type stars based on the Two Micron All Sky Survey database 

      Ortiz, Roberto Pereira; Malacarne, Marcio; Wilhelm, Ronald; Costa, R. D. D.; Rossi, Silvia; Maciel, Walter Junqueira (2007) [Artigo de periódico]
      We report the results of a spectroscopic survey of blue stars near the south Galactic pole, selected according to their color indices in the 2MASS database. The main scope of this work is to determine the nature of the ...
