THE NON-UNIFORM ROTATION OF THE SUN AND ITS MAGNETIC FIELD. VCA Ferraro, Ph.D. i. Introduction and Summary.-The problem of the uniform rotation of the Sun in its own magnetic field has been considered by Cowling; * the case considered by him was essentially that of a mass of ionized gas rotating as a rigid body in the presence of an axially symmetrical magnetic field whose axis coincided with the axis of rotation. Cowling showed that in this case a polarisation of the gas would be set up, but it is to be noted that this could only subsist if the magnetic field …
