Numerical Simulations of Supernova Dust Destruction. I. Cloud-crushing and Post-processed Grain Sputtering

Understand

We investigate through hydrodynamic simulations the destruction of newly-formed dust grains by sputtering in the reverse shocks of supernova remnants.

• Using an idealized setup of a planar shock impacting a dense, spherical clump, we implant a population of Lagrangian particles into the clump to represent a distribution of dust grains in size and composition.
• We then post-process the simulation output to calculate the grain sputtering for a variety of species and size distributions.
• We explore the parameter space appropriate for this problem by altering the over-density of the ejecta clumps and the speed of the reverse shocks.
