Magnetically collimated winds from accretion disks
Abstract
A steady, axisymmetric wind from a magnetized accretion disk is studied by applying a numerical scheme developed for the stellar wind modeling (Sakurai, 1985). As in the magnetic stellar winds, the collimation of the wind toward the rotation axis is seen in the wind from a disk. The driver of the collimation is the toroidal magnetic field which develops in the wind due to the rotation of the disk. Magnetic winds from rotating disks can therefore naturally lead to the formation of collimated jets, which are found in star-forming regions and in extragalactic radio sources.
