✦ Synopsis

In this paper we investigate the effects of condensation and thermal conduction on the formation of Kippenbahn-Schlfiter (K-S) type prominences in quiet regions (QP) due to symmetric mass injection. To implement this investigation, a self-consistent, two-dimensional, non-planar, time-dependent magnetohydrodynamic (MHD) simulation model is developed. In the model, we use various values of the injection velocity, density, and magnetic field strength to determine the most favorable conditions for the QP formation. Based on these simulation results, we find that the formation of a K-S-type field configuration should be considered as a dynamic process, which needs both condensation and mass injection to supply enough mass to maintain such a configuration to complete the formation process of quiescent prominence.
