Question

Quizplus · Accepted Answer

The making of abundant iron nuclei is typical of Type II supernovae, where massive stars undergo a violent explosion at the end of their lives. Planetary nebula ejection, the helium flash, and novae events do not involve the production of large amounts of iron nuclei. Type I supernovae, on the other hand, produce primarily lighter elements such as oxygen and carbon. The making of abundant iron nuclei is a characteristic of Type II supernovae, as they are the explosions of massive stars that have gone through fusion up to iron in their cores.
