1 Otero, Sebastian Alberto Microquasar. Relativistic jets from a 20 solar mass-black hole.
2 GCVS Team SS 433. B-V = +2.0. Associated with the SNR W 50. Mean light varies in the range 14.0 - 14.6 V according to the elements Max = 2443662.5 + 165.5d*E [S.A.Gladyshev, V.P.Goranskij, N.E.Kurochkin, A.M.Cherepashchuk, Astron. Tsirk. N1146, 1980.]. The depth of Min I varies from 0.2m to 0.9m V, the depth of Min II varies from 0 to 0.4m V. Two systems of H, HeI, HeII emission lines are observed in the spectrum: the "stationary" system corresponding to Vr changes from 300 to 150 km/s with P = 13.1d, and the "relativistic" one, corresponding to Vr changes from +50000 to -35000 km/s with P = 165.5d. The spectral study [P.Murdin, D.H.Clark, P.G.Martin, MN 193, 135-151, 1980.]. The system apparently consists of an O - B star filling its inner Roche lobe and a compact object surrounded by an accretion disc wich is precessing with P = 165.5d. Two jets consisting of dense condensations of matter emerge from the system with relativistic velocity (0.27 c) in opposite directions. The luminosity of the disc amounts to not less than 60% of the total luminosity of the system [A.M.Cherepashchuk, MN 194, 761, 1981., N.G.Bochkarev, E.A.Karitskaya, N.E.Kurochkin, A.M.Cherepashchuk, Astron. Tsirk. N1147, 1980.]. The object may be a former supernova which bursted not more than 10**4 years ago.
