Here, energy is deposited globally in both the electrons and the ions, by taking F ⁱ _g0 = F ^e _g0 = 2.5 × 10 ⁵ erg cm ⁻² s ⁻¹, H _g = 1  R _☉. Dotted curves: "interplume" solution without base heating ( F ⁱ _b0 = F ^e _b0 = 0). Solid curves: "plume" solution with strong base heating ( F ⁱ _b0 = F ^e _b0 = 2 × 10 ⁵ erg cm ⁻² s ⁻¹, H _b = 0.01  R _☉). Top panel: u( r) (in units of 100 km s ⁻¹), T _e ( r) (in MK), and T _i ( r) (in MK). Bottom panel: n( r) (cm ⁻³) and n( r) u( r) (in units of 10 ⁵ cm ⁻² s ⁻¹).
