We present analytical and numerical models of a normal-polarity quiescent prominence that are based on the model of Pikelner (Solar Phys.17, 44, 1971). We derive the general analytical expressions for the two-dimensional (2D) equilibrium plasma quantities such as the mass density and gas pressure, and we specify magnetic-field components for the prominence, which corresponds to a dense...
We generalize our analytical and numerical models of the solar flux tube on twisted magnetic-field lines. The basic equations and numerical methods have much in common with those of Murawski et al. (Astron. Astrophys.577, A126, 2015); the new and important issue is the twisted magnetic-field component that couples explored torsional Alfvén and magnetoacoustic waves. In these models we specify a magnetic-flux...
