There is no atoms in star that are more havy that iron becouse to fuze lighter atoms to uranum or plutonium u need to add energy more u get when u destroy havy atoms, u gain energy fuzing H into He Li etc to iron becouse fuzing into iron still gives energy but fuzing into more havy atoms drains energy :)
I dont think stars come from pulsars
Nvm, just looks like the original
now, it works normally +1
