Left: Meridional cross sections showing steady-state properties (averaged over ∼5 ms) of the wind models B3P1 (left) and B3P1.8 (right). The top three rows (from top to bottom) show the fractional contributions of the specific kinetic energy (≈ −u_t − 1 at large distances), magnetic energy (−u_tb²/4πρ), and thermal enthalpy (−u_t(ϵ + P/ρ)), to the total specific wind energy ﹩{ \mathcal B }﹩ (defined in Equation (A3)). The bottom row shows the ratio of electromagnetic ﹩{\dot{E}}_{{\rm{EM}}}﹩ to kinetic ﹩{\dot{E}}_{{\rm{K}}}\equiv (W-1){\dot{M}}_{{\rm{iso}}}﹩ power. The top row shows fluid-velocity field lines, whereas the bottom three rows show the magnetic field lines. Right: Angle-averaged radial profiles of isotropic-equivalent luminosities along the y = 0 plane for three models: B3P1 (solid, 0° ≤ θ ≤ 30°), B.6P1 (dashed, 0° ≤ θ ≤ 30°), B3P1.8 (dotted, 0° ≤ θ ≤ 90°). We show separately the Poynting luminosity (blue), kinetic luminosity (green), thermal luminosity (red), and their sum (black).
