The Expulsion of Stellar Envelopes in Core‐Collapse Supernovae
We examine the relation between presupernova stellar structure and the distribution of ejecta in core-collapse supernovae, assuming adiabatic, spherically symmetric flow. We develop a simple yet accurate formula for the blastwave shock velocity, and demonstrate that the entire final density distribution can be approximated with simple models for the final pressure distribution, along with the approximate shock-deposited entropy, in a way that matches the results of simulations. We find that thedoi:10.1086/306571 fatcat:v7dlqwbeqbcrlirzn2vodsmgau
