Isocontours of ψ = 1 in the X − Z plane for the Soloviev solution with different geometries. The upper panel illustrates the impact of the triangularity parameter τ on the isocontour ψ = 1, while the lower panel, characterizes the influence of the elongation parameter σ for a torus with a = 1 R_⊙ and R₀ = 2.5 R_⊙, centered at (0,0,0). The marker “+” indicates the center of the torus, while the dot marker corresponds to x = R₀. In the top panel, σ is kept constant at 1.4 and in the bottom plot, τ is constrained to 0.
