A model for quiescent solar prominences with normal polarity

A class of two-dimensional models of solar quiescent prominences, with normal polarity, is presented. These represent an extension to the Kippenhahn-Schlueter model for which the prominence configuration matches smoothly onto an external nonpotential coronal solution of a constant alpha field. Using typical prominence values, a model is constructed which also matches the coronal conditions. It is found that the magnetic field component along the prominence influences the internal structure of the prominence. A simple extension to the basic models is indicated as a means of taking a lower boundary of the prominence and eliminating parasitic polarities in the photosphere.
