Do stars exert iron or turn into iron?

Answer 1

During the explosion of a nova or supernova, the nuclear fusion process fuses lighter elements into heavier ones, which create all the elements heavier than carbon. Iron is one of the elements created.

Iron holds a special place in this process, because it is at the trough of the "packing fraction" curve. When lighter elements like hydrogen fuse into heavier elements like helium, or helium into carbon, energy is released. This is the process that powers the Sun and all the stars. This holds true for all the elements up to iron; energy is released in fusion.

But when iron fuses into anything heavier, energy is ABSORBED in the reaction. So when the nova reaction creates gold, or silver, or uranium or nay heavy element, it's sucking up the energy that the star needs to keep from collapsing. This is what causes the supernova to explode; the star's center is IMPLODING while the outer layers are exploding.

Answer 2

No planets never turn into stars. Stars are extremely large masses of gas mainly comprised of Hydrogen and Nitrogen and must be roughly 4 times larger than Jupiter fornuclear fusion to occur. Nuclear fusion is the process when atoms are crushed to form other elements during this process large amounts of energy are released in light and heat, thus a star.

Answer 3

If it is a big enough star it goes into supernova. If the Star is like our sun than it would rapidly expand. The inner layer would push everything away and all that would remane is a dense core.

Answer 4

Stars create elements up to iron through nuclear fusion in their cores. Iron is the most complex element that stars can create through fusion reactions. When stars reach the end of their life cycles, they can explode in supernova explosions, releasing newly formed elements, including iron, into space.
