These results support the operation of the convective supernova engine via neutrino heating in the supernova that produced Cassiopeia A. The metal composition of the plumes agrees well with predictions for strongly neutrino-processed proton-rich ejecta 2, 5, 6. We found that the observed Ti/Fe and Cr/Fe mass ratios require α-rich freeze out, providing evidence of the existence of the high-entropy ejecta plumes that boosted the shock wave at explosion. Here we report observations of such elements-stable titanium (Ti) and chromium (Cr)-at a confidence level greater than 5 standard deviations in the shocked high-velocity Fe-rich ejecta of Cassiopeia A. Detecting the signatures of specific elements synthesized in the high-entropy nuclear burning regime (that is, α-rich freeze out) would constitute strong substantiating evidence.
Outwardly protruding iron (Fe)-rich fingers of gas in the galactic supernova remnant 3, 4 Cassiopeia A seem to match this picture. Recent multi-dimensional simulations suggest that high-entropy buoyant plumes help massive stars to explode 1, 2. The list of all annotations to SIMBAD objects can be found here.
