supernova (tip II)

supernova (tip II)

An enormously bright, energetic, catastrophic explosion that occurs at the end of the lifetime of a massive star whose core collapses. A star must have at least nine times the mass of the Sun to undergo a core-collapse supernova. The extreme heat generated by the explosion makes elements heavier than iron, this is called supernova nucleosynthesis. See also r-process and s-process, and stellar nucleosynthesis.
