      We observed the pulsating hydrogen atmosphere white dwarf G 185-32 with the Whole Earth Telescope in 1992. We report on a weighted Fourier transform of the data detecting 18 periodicities in its light curve. Using the ...
    • The pulsations of PG 1351+489 

      Redaelli, M.; Wood, Matt A.; Kepler, S. O.; Costa, Jörge E. S.; Winget, Don Earl; Handler, Gerald; Castanheira, Bárbara Garcia; Kanaan, Antonio; Fraga, Luciano; Henrique, P. (2011-08-01)
      PG 1351+489 is one of the 20 DBVs - pulsating helium-atmosphere white dwarf stars - known and has the simplest power spectrum for this class of star, making it a good candidate to study cooling rates. We report accurate ...
