What We Can Learn from Ejecta in Supernova Remnants
Abstract
The ejecta in supernova remnants is the most direct link to information about the progenitor system of the pre-supernova star. The abundances of various elements, the spatial velocity of the ejecta blobs, the temperature of the reverse-shocked plasma; all of these are important diagnostics from the ejecta. In this talk, I will give an overview of how we can use studies of the ejecta in SNRs to learn about the evolutionary stage of the remnant and the connections to the progenitor system. I will highlight recent results and discuss avenues for future study with upcoming missions such as JWST, XRISM, and Athena.
