Properties of the bipolar outflows at t = 3510 d. Shown are the density ρ in (a) and (b), the absolute value of the magnetic field |B| in (c) and (d), the rϕ-component of the Maxwell stress tensor normalized by the centrifugal force ${\stackrel{\sim }{M}}_{r\varphi }=B_r{B}_{\varphi }/4\pi \rho v_{\varphi }^2$ in (e) and (f), the absolute ratio between the poloidal and toroidal magnetic field components |B_pol/B_tor| in (g) and (h), the poloidal Alfvén Mach number ${\mathcal{M}}_{\mathrm{Alfven},\mathrm{pol}}=v_{\mathrm{pol}}\sqrt{4\pi \rho }/B_{\mathrm{pol}}$ in (i) and (j), the inverse plasma beta β⁻¹ = |B|²/8πP_gas in (k) and (l), and the specific enthalpy h in (m) and (n). The gray contours in the zoomed-in plots in the left column correspond to the transition from sub- to super-Alfvénic flows (i.e., the Alfvén surface).
