Scientific paper

From a new spectroscopic orbit of the A-type WUMa system V 1073 Cyg, based on Reticon observations, the following values are found: V0 = -0.8 +/- 1.1 km/s; Kp = 66.7 +/- 1.3 km/s; Ks = 210.2 +/- 1.2 km/s; and mp/m sub s = 3.15 +/- 0.07. Combining results on the mean secondary temperature, filling factor, and inclination with the spectroscopic orbit, the physical parameters of V 1073 Cyg are obtained.
