VB AB (10.26m V, 12.3m V; A = 0.1127", P = 29.33 Y [J.Russell, G.Gatewood, AJ 85, N9, 1270, 1980.]); mu = 0.67", P = 113deg; A-SB 2 (mAb - mAa = 0.6m, P = 3.275631d [F.Fekel Jr., B.W.Bopp, C.H.Lacy, AJ 83, 1445, 1978.]). Probably all the three components of the system are variables of the UV Cet type, and according to [W.Krzeminski, "Low Luminosity Stars", ed. by Sh.S.Kumar, 57, 1969.] also of the BY Dra type. The range of combined brightness of the system is given in the Table. Really the flare of AB component was observed in the spectrograms [F.Fekel Jr., B.W.Bopp, C.H.Lacy, AJ 83, 1445, 1978.]. |
