Equilibrium configuration of a rotating (Ω₀) and magnetically twisted (B₀(0, B_φ0, B_z0)) cylindrical solar plasma structure with radius a and cross section A₀ = πa². The plasma structure with an equilibrium pressure denoted by p₀ is embedded in a zero-β medium with an equilibrium magnetic field represented by B_z0e. The solar gravity is represented by g, while viscosity is represented by ν.
