Description

Near infrared light curves of the dwarf nova OY Carinae are presented. The light curves differ from the optical curves of this system in showing a much shallower primary minimum and in addition, a secondary minimum which is not observed at optical wavelengths. These light curves can be understood in terms of the secondary contributing a substantial proportion of the infrared radiation. OY Carinae is the shortest period cataclysmic variable in which the secondary has been directly observed. The K magnitude of the secondary is used to derive a distance of d = 121 +- 20 pc for OY Carinae. (author)
