31 Cyg. Probably enters a common system with V1488 Cyg (32 Cyg). VB A (B 13.0m, 36.8", 332deg; C 6.99m, 107.0", 174deg; D 5.0m, 338", 323deg). d = 0.0151P. Interferometric binary eclipsing system (A = 0.08", E = 0.15 [R.H.Wilson, AJ 55, 158, 1950.]; 0.035", 141.8deg, 1980.4). The epoch of eclipse of the component of the spectral type B4 by the component of the type K4 is given in the Table. The amplitude strongly varies depending upon the wavelength: A(lambda 6560 A) = 0.03m, A(lambda 3530 A) = 1.80m [R.H.Bloomer, Jr., F.B.Wood, PASP 85, 348, 1973.]. |
