Abstract (from CDS):

We report Galaxy Evolution Explorer NUV and optical follow-up observations of the cataclysmic variable V455 And at 3 years past its large amplitude dwarf nova outburst. Orbital and superhump variations are evident in the NUV and optical light curves. We clearly detect the spin along with a photometric variation that we tentatively attribute to non-radial pulsations in the Discrete Fourier Transforms at both wavelengths. The increased amplitude of the spin and pulsation in the NUV versus the optical implies an origin near the white dwarf. The shorter pulsation period after outburst is indicative of a white dwarf that remains hotter than at quiescence.
