The eclipse-related phase shifts in DQ Herculis and UX Ursae Majoris. Petterson, J. A. Abstract The paper describes a model for a cataclysmic-variable binary system in which a large accretion disk reflects radiation from a progradely rotating source on or near the white dwarf surface, thus reproducing rapid oscillations in the optical radiation. The model reproduces the phase shift and amplitude variations of the DQ Herculis oscillations during eclipse very well. The same model, with a progradely rotating source, also reproduces the completely different eclipse-related phase shift behavior of UX Ursae Majoris, when it is viewed at a somewhat smaller inclination angle (about 75 deg).
