Scientific paper

High-speed spectroscopy and photometry for V803 Cen reveal lines which are slightly and variably asymmetric. The line widths can be qualitatively explained by Stark broadening, and it is suggested that the lines may have been formed in an accretion disk of low inclination. The asymmetry in the line profile appears to vary on a time-scale of several hours or longer, and it may indicate the presence of a noncircular, perhaps elliptical, outer edge to the accretion disk.
