| + | Paris-Durham (PD) 50 km/s shock into WNM. | ||
| + | |||
| + | To initialise PD we run a time evolution of a parcel of gas at density n=0.1 cm-3, irradiated with an ISRF G0=1, and cosmic ray rate zeta=10^-16 s-1. | ||
| + | |||
| + | This is the chemical evolution of that parcel, showing the electron fraction reaching ~10^-2. | ||

| + | |||
| + | This is the temperature evolution of that parcel, reaching T~10^4 K. | ||
| + | |||
| + | {{:01_slabtemp.png?650|}} | ||
| + | |||
| + | Using the result of the above runs as the input (chemical abundances, temperature) for PD, here is a 50 km/s shock. This is the temperature and hydrogen density profile. | ||

| + | For comparison with mappings (Sutherland and Dopita 2017), several models were run. This is the temperature profiles of the PD shock (black), mappings with most basic settings (blue), basic + cosmic ray rate zeta=10^-17 s-1 (orange), basic + UV field (Mathis field, 9.50918E+09 phots/cm^2/s), basic + dust calculation. | ||
