Top panels: the gas temperature profiles (T w [K]; left panels) along with the adiabatic prediction (red dashed line), and the line emissivities (ϵ i [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) cases from Paper II and NPI cases (Section 3), for wind speed V = 457 km s−1, metallicity ﹩\hat{Z}\equiv Z/﹩ Z = 0.5, mass-loading rate ﹩{\dot{M}}_{\mathrm{sc}}=0.607\times {10}^{-2}﹩ M yr−1, cluster radius R sc = 1 pc, and age t = 1 Myr, surrounded by the ambient medium with density n amb = 100 cm−3 and temperature T amb determined by CLOUDY, producing a wind model in the CB mode (described in Section 2). The O VI and C IV emissivity profiles predicted by the CPI model are shown by dashed lines in the NPI panel. Bottom panels: the hydrogen density profiles (n H [cm−3]; left panels) along with the adiabatic prediction (red dashed lines), and the ionic fractions (F i ; 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, dashed–dotted, and solid lines (gray color), respectively. The ionic fractions predicted by the CPI model are plotted by dashed lines in the NPI panel. The plots for all the models (192 images) are available in the interactive figure in the online journal. The interactive figure includes menu options to browse all the models by varying V , Z/Z , ﹩{\dot{M}}_{\mathrm{sc}}﹩, and n amb.
