VB A (B 14.0m, 21", 224deg). d = 0.037P. Survey of the physical properties of the system [O.Struve, PASP 68, 27, 1956., K.O.Wright, JRAS Can 49, 221, 1955., H.A.Abt, ApJ 126, 138, 1957., I.M.Kopylov, R.N.Kumajgorodskaya, Izv. Krymsk. Astrofiz. Obs. 29, 251, 1963., M.Hack, Mem SAIt 32, F.4, 1961==Milano-Merate Contr N185, 1962., Kh.Albo, Tartu Publ 45, 284, 1977.]. The spectrum probably varies even outside eclipses. The eclipses are probably due to a disk of gas and dust surrounding the hot companion. The brightness has physical fluctuations with the amplitude up to 0.24m and the cycle about 110d [C.M.Huffer, ApJ 76, 1, 1932.] which hinder revealing the possible Min II. Similar cycle was discovered also in the fluctuations of Vr. |
