Scientific paper

We have obtained the first time-resolved photometry of the double degenerate white dwarf/white dwarf binary star WD 0957-666. Light curves of the binary are essentially indistinguishable from light curves of nonvarying field stars. We detect no eclipses that have amplitudes larger than ~0.04 mag. Using a simple geometric model predicting eclipse behavior in WD 0957-666, we use this result (along with a lower limit by Moran, Marsh, & Bragaglia) to constrain the system inclination to i~62deg-86deg.
