### On Nonshearing Magnetic Configurations in Differentially Rotating Disks

Abstract:

A new class of disk MHD equilibrium solutions is described, which is valid within the standard local (shearing sheet'') approximation scheme. These solutions have the following remarkable property: velocity streamlines and magnetic lines of force rotate rigidly, even in the presence of differential rotation. This situation comes about because the Lorentz forces acting upon modified epicycles compel fluid elements to follow magnetic lines of force. Field line (and streamline) configurations ...
