Question
If the Fe is the heaviest element "produced"/fusioned in a star. How are "produced" the others, which are heavier than Fe?
The elements heavier that iron are produced in the extreme conditions of heat and pressure that take place during a supernova explosion. This same supernova mechanism also injects the gas enriched with heavy elements back into the interstellar gas clouds.
