Gilliland, R. L. ; Kemper, E. Abstract The short-period eclipsing binary system and recurrent nova WZ Sge (1913, 1946, 1978) was observed spectroscopically during its renewed 1978 December outburst. Absorption-line radial velocities and H-alpha emission profiles suggest a circumbinary gaseous disk. A schematic model is presented to explain both the observed radial velocities and the photometric properties of WZ Sge during outburst. The model also accounts for 'superhump' phenomena in SU UMa type dwarf novae.
