Simulating the Evolution of Supernova Created Dust: Decoupling, Destruction and Escape

It has now been well established the core collapse supernovae (SN) create significant quantities of dust. The dust is formed in cold, dense ejecta clumps and has been observed in several young supernova remnants such as Cas A. Much of the dust detected in supernova remnants, however has not yet encountered the reverse shock, which will in time reach the center of the remnant. Thus it is unclear how much of the dust that has been created will survive the shock and reach the interstellar medium. We present the results of numerical simulations of the evolution of dense clumps and dust in a Cas A-like supernova remnant. We follow the dust that starts in the clumps as it propagates through the remnant and suffers sputtering that erodes the grains. We will present our results regarding the fraction of grains that survive to reach the remnant shell after the forward shock had gone radiative. This provides a comprehensive estimate of SN-created grain survival.
