Abstract (from CDS):

We study the splitting of pulsations of the ZZ Ceti (DAV) white dwarf G 117-B15A using 96 h time series photometric data obtained with the Whole Earth Telescope in March 1990. We find that all the modes, except the main, have fine structure, but not according to the predictions of simple rotational or magnetic splitting of non-radial g-mode pulsations. We also revise the time-scale for period change using all the data up to 1995.
