Effect of depositing energy in the ions but not the electrons, by taking F ⁱ _g0 = 5 × 10 ⁵ erg cm ⁻² s ⁻¹, H _g = 1  R _☉, F ^e _g0 = F ^e _b0 = 0. Dotted curves: solution without base heating, F ⁱ _b0 = 0. Solid curves: solution with strong base heating, F ⁱ _b0 = 4 × 10 ⁵ erg cm ⁻² s ⁻¹ and H _b = 0.01  R _☉. Top panel: profiles of bulk flow speed u (in units of 100 km s ⁻¹), electron temperature T _e (in MK), and ion temperature T _i (in MK) as a function of heliocentric distance r. Bottom panel: logarithmic profiles of number density n = n _e = n _i (cm ⁻³) and number flux density nu (in units of 10 ⁵ cm ⁻² s ⁻¹) as a function of r.
