Description
The Whole Earth Telescope, under operation by the Delaware Asteroseismic Research Center, have obtained multi-site observations of two pulsating white dwarf stars. The DAVs R808 and G29-38 both show an abundance of excited modes, mostly clustered around 1050μHz. We present the Fourier analysis of both multi-site campaigns, present the measured periods, discuss their combination modes, and show that amplitude modulation is present in these stars.
