I do not know about this iron business.

Iron cannot in a normal state, be in gaseous form or any other form but a solid.

Fe is more of a planetary building block than a star maker. I am not saying that it does not play a role, but I can't see the element doing what this writer says.

Huh? Iron is fairly easily melted, so it is not always in a solid. Anyone who does welding melts iron frequently. Use a cutting torch? Then you're burning iron in oxygen. That's where all those sparks come from. At a high enough temperature, iron vaporises, as well.

Exactly! This all sounds very tin-foily to me. An iron-rich star formed around a neutron star (if such a thing is even possible) ought to be considerably heavier than a hydrogen star. But we know what the sun weighs and that measurement agrees with it being mostly hydrogen.

The center of the earth is iron, when the earth was a molten ball of goo, the iron on the surface slowly collapsed inward to form its core and its magnetic field, while the lighter materials formed the earth's crust and mantle, why can't the same be true for the sun?

"Iron cannot in a normal state, be in gaseous form or any other form but a solid."

I don't know squat about this, but I'm prettty sure that whatever is at the core of the sun probably is not "in a normal state."

All elements can exist in a plasma state.

Take an iron hand tool and drop it between the positive and negative leads on a car battery. Then run away quickly, avoiding the gaseous and molten iron.
