WebOct 14, 2009 · Second, most stars don't even fuse all the elements up to iron. Third, for the stars that do fuse elements up to iron, the heavy elements are almost always blown off in the ensuing supernova explosion, leaving a neutron star. Again, I don't see any way this neutron star could become an "iron star". Jun 7, 2009 #3 protonchain 97 0 WebIf the star isn't large enough, nuclear fusion may stop, before the core of the star is fused to iron, since very high temperature (more than 2 billion Kelvin) and pressure are needed to fuse silicon to iron. This way the core may collapse earlier.
