Superwinds and Superbubbles

Hydrodynamic Simulations

Hydrodynamic Simulations with the Non-equilibrium Atomic Chemistry and Cooling package MAIHEM built on the adaptive mesh hydrodynamics code FLASH.

From top to bottom: the temperature and density profiles of the superwinds on a logarithmic scale with the wind terminal speeds of V_∞ [km s⁻¹] (blue, red, and orange solid line). The ejected gas has metallicity Ẑ ≡ Z/Z_⊙ and mass-loss rate Ṁ_sc [M_⊙ yr⁻¹]. The SSC has radius R_sc = 1 pc and age t = 1 Myr. The physical conditions of the ambient medium are n_amb [cm⁻³] and T_amb based on the thermal profile derived by its CLOUDY photoionization model. The different regions separated by dotted lines: (a) freely expanding wind, (b) shocked-wind, (c) shell, and (d) ambient medium. The adiabatic temperature and density profile for each model are shown by dashed lines.
