Description
The paper presents the results of high-time-resolution white-light photometry of H2215-086 obtained at Las Campanas Observatory and Cerro Tololo Inter-American Observatory during 1985-1987. Descriptions of periodic features, including power spectra due to rotational and orbital modulation, are presented as well as quasi-periodic features. It is found that H2215-086 displays large-amplitude modulations in its optical, IR, and X-ray emission on the 20.9 min rotational period of the white dwarf. Possible sites for this emission are discussed. 31 refs
