Using AMR to Simulate the 3-D Hydrodynamic Interaction of Supernova Shocks with Interstellar Gas Clouds

We study the 3-D hydrodynamic interaction of supernova shock fronts with interstellar clouds to investigate the evolution, the morphology and the deviations from equilibrium of ionization. To this end, we use the FLASH code including PARAMESH, an advanced and versatile parallel adaptive mesh refinement package. We present here the preliminary results obtained modeling a representative case of a Mach 50 shock impacting on an isolated cloud with density contrast χ = 10 with respect to the ambient medium. The preliminary analysis of the non-equilibrium ionization (NEI) effects on the ionization stages of oxygen, and iron is discussed.
