Model disc wind structures using different MDWs. Left: hydrogen number density n. Middle: poloidal velocity v_p. Right: toroidal/rotational velocity v_ϕ. From top to bottom, we show #MDW 1, 2, 3, 4 and 5. Calculated assuming the HD 52961 system and i = 70°, r_in = 5 R₂, r_out = 0.99 R_RL, 2 and Ṁ_in = 10⁻³ M_⊙/yr. We note the slight discontinuity at a fixed polar angle in the n and v_ϕ profiles. This is an artefact from the leapfrog integration performed over the Alfvén surface in the MDW solutions (Jacquemin-Ide et al. 2019), in combination with our projection onto Cartesian coordinates.
