Abstract • The authors present optical and infrared photometry from the 1985 May superoutburst of OY Carinae, and estimate the temperature and area of the superhump region to be approximately 8000K and ≡1020cm2 respectively. There is evidence for extended vertical structure in the disc, possibly analogous to that which causes X-ray dips seen in low mass X-ray binaries. The authors show that the size of the O-C variations of the eclipse timings are significantly smaller than previously thought.
