IV Superabundance energy --Lots of excess energy and lots of High energy matter and particles Create elements heavier than Iron Source of all elements heavier than Iron V blast spreads all of this material through space sseds: the interstellar medium force of explosion can kick start nearby star formation Population I Star metal rich It is a star that has been seeded by either a) a supernova explosion all elements B) a planetary nebula C and N and O Other ways for stars to die.
