A note on the rotational motion in quiescent prominences

Abstract

Following an earlier paper (Pande & Bondal 1991) we have, on the basis of Kippenhahn and Schluter's magnetohydrostatic model of a quiescent prominence, attempted to study the effect of a rotational velocity field in the vertical plane. However, it was not possible to establish whether the rotational velocity field in the vertical plane could be accomodated in the model. We now find that the rotational motion is possible both in the vertical and horizontal planes, without violating the basic assumptions in that model; this is a modification over earlier conclusion.
