2D slices of the plasma density for χ = 60°. Top: rθ-plane containing the magnetic axis at the phase ϕ = Ωt. Bottom: rϕ-plane at the equator (θ = 90°). The radius is expressed in units of R_LC. Right panels: zoomed-in views of the regions delimited by the white boxes drawn on the left panels. The striped wind region is contained within π/2 − χ ≤ θ ≤ π/2 + χ (white dashed lines).
