Scientific paper

Photoelectric UBVR observations and photographic BVR observations of the variable AC Cnc have been carried out. The analysis of the observations showed that the system AC Cnc consists of a cold K4 V star and a white dwarf surrounded by an accretion disc. The distance between the components was estimated as 0.01 a.u.; the size, brightness and temperature of the disc were estimated to be 0.5 R_sun;, 1.3×1033erg/s and 104K, respectively. A possible connection with the X-ray object H 0850+13 is discussed.
