    Neither. It is the production of iron, not the iron itself, that disrupts a star. If you were to dump a boat load of iron into a healthy star it would have no significant effect.

    Remember that the Sun is loaded with iron right now. There is one iron atom for every 35K atoms of hydrogen. The Sun formed out of the same nebula that Earth did and has 14,500 times as much iron in it than Earth does.

    When a very massive star begins producing iron in it's core, that's it's death warrant... Iron can't be fused into heavier elements *and* release energy at the same time - it *takes* energy to fuse elements heavier than iron...So - the fusion reaction at the core stops - and, the star collapses on itself. Without the explosive force of fusion countering the force of it's own gravity, the star falls in on itself, then rebounds - exploding in what we call a supernova...

    The end result is that it's core is crushed - down to either a neutron star, or possibly a black hole.

    Iron kills the fusion in the core of the star, because no star can generate the pressure and temperature needed to fuse iron into a heavier element. When the fusion in the core shuts down, then gravity wins and the star collapses. Depending upon the mass of the star it becomes a Dwarf Star, a Neutron Star, or a Black Hole.

    Iron tends to weaken stars.

    Because it is not fusable.

    And it interferes with the fusion of other lighter elements.

    Lighter elements like Hydrogen, Helium, Carbon, Nitrogen and Oxygen fuse to form heavier atomic weight elements.

    That process ends with iron.

    When the amount of iron in a star reaches a certain level, the fusion process stops and the star collapses.

    Either forming a black hole or having a supernova.

    Iron is the end of the line in stellar fusion.

    If a star attempts to fuse iron, it dies.

      Not "if", but "when".
