Observations of UU Cancri. Kalv P., Oja T., Harvig V. <Journal Astronom. Data, 13, 2 (2007)> =2007JAD....13....2K
ADC_Keywords: Stars, double and multiple ; Photometry, UBVRI Keywords: UU Cancri - Photometry - binaries Abstract: We present UBVR photometric observations of the 96-day binary system UU Cancri (K4 III) obtained in 1972-1994. A relatively large scatter in the orbital light curves turned out to be intrinsic with a modulating cycle lasting at least 8000 days. Using all available archived photographic and visual observations covering nearly 100 years, we find the orbital period of the system to be constant. This fact, together with the pattern of the colour curves, makes the existence of a powerful accretion disk in the system improbable. Description: UU Cancri was observed with the Tallinn 50-cm telescope (BV from 1972, UBVR from 1980), the Kvistaberg 40-cm telescope (UBV from 1985), the 60-cm telescope of the Royal Swedish Academy of Sciences at Observatorio Astrofisico del Roque de los Muchachos, La Palma Canary Islands (UBV from 1991) and 2.5-m Nordic Optical Telescope (UBVRI on seven nights from 1990). Up to 1994 in total 234 observations (one normal point per night) have been obtained.
