{synonym}
Collapse of a massive stellar core can launch an explosion that ejects material processed by hydrostatic and explosive burning. Whether an explosion succeeds, and how much material escapes instead of falling back, depend on the core and envelope structure. A <failed supernova> can retain much of the nucleosynthetic core; initial stellar mass alone is not a complete prediction.
