| description | In the present work we have com-
puted the thick accretion disk (the accretion disk with
radiation pressure) for the case of undefined precession
over very long time (more than 14 precession periods).
The calculations show that in this case the origin of
the ON-states and OFF-states are strong irregular
in time. The calculations also show that the jet’s
launches are taking place very suddenly over 7 ÷ 20
minutes of the orbital time. The jet’s launches over
OFF-states occurs discrete as it is observed in real
microquasars. |
