Figure 3. Top Panels: The hydrogen temperature profiles (TH [K]; left panels) along with the adiabatic prediction (red dashed line), and the line emissivities (εi [erg cm−3 s−1]; right panels) of the superwind models on a logarithmic scale, from top to bottom, in the CPI (collisional ionization+photoionization) and NPI (non-equilibrium photoionization) cases (described in §3), for wind terminal speed V∞ [km s−1], metallicity Ẑ ≡ Z/Z⊙, mass-loss rate Ṁsc [M⊙ yr−1], cluster radius Rsc = 1 pc, and age t = 1 Myr, surrounded by the ambient medium with density namb [cm−3] and temperature Tamb determined by CLOUDY, producing a wind model in the mode denoted in the title (described in §4). Bottom Panels: The hydrogen density profiles (nH [cm−3]; left panels) along with the adiabatic prediction (red dashed lines), and the ionic fractions (Fi; right panels) on a logarithmic scale for the CPI and NPI cases. The start and end of the hot bubble (region b), the end of the shell (region c), and the Strömgren radius are shown by dotted, dashed, dash-dotted, and solid lines (gray color), respectively.
