Hydrodynamic Instability of Ionization Front in HII Regions: From Linear to Nonlinear Evolution

We investigate hydrodynamic instabilities at an ionization front in a radiatively driven molecular cloud, using two-dimensional hydrodynamic simulations, including absorption of UV radiation from OB stars, recombination in HII gas, and radiative molecular cooling. We find a strong stabilization mech...
