| dc.description | We present an analytical model for the magnetic flux surfaces for rapidly rotating magnetized young stellar objects which is based on ideal, stationary, axisymmetric magnetohydrodynamics. The resulting cold wind solutions reproduce observed wind velocities of a few hundred \kms$ $ and the outer jet radi us for a collimated jet of several thousand stellar radii. The theory of axisymmetric magnetospheres around rapidly rotating stellar sources is outlined including electric fields due to the rapid rotation. Gravity of the central object is consistently built into this theory. A consistent wind theory is developed which contains the Newtonian theory as a classical limit. Current--carrying plasma flows will lead to a collimation of the magnetospheric structure into a cylindrical shape. We show that the asymptotic structure is essentially determined by electric forces in the pinch equation, and not by centrifugal and pressure forces. | |
