Title: Why does conversion of its core to iron have to mark the end of a star's life? Post by: barry on Aug 3, 2013 Why does conversion of its core to iron have to mark the end of a star's life? Which stars can end up with iron cores?

The formation of an iron core ends the normal life of a star because iron cannot be fused into heavier elements and produce energy, as previous fusion reactions have done. In order to fuse iron, energy must be provided. The star, at this point in its evolution, has finally run out of energy sources in its core.
