Abstract

Comparison of five X-ray observations of FO Aqr reveals the morphology of the X-ray light curve changes considerably with time. Power spectra of the 1988 Ginga and 1993 ASCA data reveal a sideband component, whereas the 1990 Ginga observation does not. This suggests the amount of disc-overflow accretion can vary with epoch. From the structured Ginga and ASCA spin folded light curves the authors infer the presence of complex, multicomponent, emitting regions near the white dwarf surface.
