Title of the communication: Acceleration of relativistic plasma at the ejection by fast rotating magnetized object.
Preliminary abstract (12 lines max.):
I intend to discuss the results of an analytical and numerical analysis of a 3-dimensional axisymmetrical time dependent plasma flow in the magnetosphere of a fast rotating magnetized object. Analytical approximate solution of the stationary plasma flow in the magnetosphere of rotator is obtained. Plasma is not accelerated and is not collimated in the limit of the fast mode surface in this flow even at fast rotation of the central object when the light cylinder is placed deeply inside the subsonic region. Numerical simulations of the time dependent version of this problem confirm this picture. Simultaneously they show that this stationary flow is not stable. Evidence that plasma is accelerated due to the instability of the flow is obtained.
