Exact solutions for helical magnetohydrodynamic equilibria. II. Nonstatic and nonbarotropic solutions

In the framework of the analytical study of magnetohydrodynamic (MHD) equilibria with flow and nonuniform density, a general family of well‐behaved exact solutions of the generalized Grad–Shafranov equation and of the whole set of time‐independent MHD equations completed by the nonbarotropic ideal gas equation of state is obtained, both in helical and axial symmetry. The helical equilibrium solutions are suggested to be relevant to describe the helical morphology of some astrophysical jets.
