Periodicities in erupting dwarf novae. Patterson, J. Abstract A comprehensive account is presented of the optical observations of coherent oscillations associated with the eruptions of dwarf novae, and a critical evaluation of the current theoretical situation is conducted. Detailed studies of oscillations in AH Herculis and SY Cancri are described, and a report is presented of the discovery of coherent oscillations and an eclipse-related phase shift in the eclipsing binary HT Cassiopeiae. Light curves at minimum and maximum light are provided, and the masses and radii of the component stars are derived from the eclipses. Attention is given to new observations oscillations in SS Cygni, supplementing the study of Patterson et al. (1978). An earlier detection of oscillations in EM Cygni is confirmed, and a list is presented of upper limits to oscillation amplitudes for 16 other dwarf novae. A summary is given of the properties of the dwarf nova oscillations, and existing models are reviewed.
