High-entropy ejecta plumes in Cassiopeia A from neutrino-driven convection

Nature, Published online: 21 April 2021; doi:10.1038/s41586-021-03391-9

The abundances of stable Ti and Cr relative to Fe observed in the Cassiopeia A core-collapse supernova remnant reveal that Ti and Cr must have formed in neutrino-driven plumes that helped to drive the explosion.
