VB (Delta(m) ~0.5m, 1.3", 11.5deg, 1972). Flares were found in the satellite UV range [J.Darius, IBVS N1429, 1978.]. Differences from typical by stars and probable "post-T Tau" nature are noted [G.H.Herbig, ApJ 182, 129, 1973., R.de la Reza, C.A.O.Torres, I.C.Busko, MN 194, 829, 1981.]. According to [P.F.Chugajnov, Izv. Krymsk. Astrofiz. Obs. 52, 3, 1974.], Min = 2441939.200 + 5.20d*E. Soft X-ray source. |
