SB2 (P = 0.27512995d [M.E.Walker, ApJ 248, 256, 1981.]). During maxima of brightness there are oscillations of light and X-ray flux with amplitudes about 0.002m V and periods changing between 7.29s and 10.90s [J.Patterson, ApJ Suppl 45, 517, 1981., R.H.Hildebrand, E.J.Spillar, R.F. Stiening, ApJ 243, 223, 1981.]. |
