An iron core cannot support a star because iron cannot undergo nuclear fusion to release energy, which is necessary to counteract the force of gravity pushing inwards on the star. This lack of energy production causes the star to collapse under its own weight, leading to a catastrophic event like a supernova.

The onset of iron fusion causes a star to become a?

The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.


What is a star with an iron core?

A star with an iron core is typically a red supergiant star that has exhausted its nuclear fuel and is in the final stages of its life cycle. The iron core forms when the star's fusion processes can no longer generate enough energy to counteract gravitational collapse, leading to a supernova explosion.


The final core element for a massive star is?

The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.


How long does it take for a massive star's core to become iron from silicon?

The process of core collapse to form iron from silicon in a massive star can occur in a matter of days to weeks. This phase, known as core-collapse supernova, is an explosive event where the iron core rapidly collapses and rebounds, leading to the synthesis of heavier elements.


Why can iron fusion not support a star because of iron?

Iron fusion cannot support a star because iron is the most stable element and cannot release energy through fusion reactions. This causes the star to collapse, leading to a supernova explosion.


Why can the fusion of iron into heavier elements not support a star?

The fusion of iron into heavier elements cannot support a star because it requires more energy than it produces, leading to a loss of energy and the collapse of the star.


Why does a stars iron core destroy that same star?

Because it basically has to do with three variables. The star's SIZE, its MASS and TEMPETURE.


What occurs when fusion creates iron in the core of a star?

The star "burns out" because iron cannot be fused. What happens then depends on the star's remaining mass:low - white dwarfmed. - neutron starhigh - black hole


Where iron comes from?

Iron is fused within a star's core. When sufficient iron has accumulated and it begins to fuse, the energy of that fusion is too great and the star explodes creating all the heavier elements.up ya bum


How is iron made from a star?

Iron is created in the core of massive stars during the process of nuclear fusion. When a star exhausts its nuclear fuel, it undergoes a supernova explosion that releases energy and elements, including iron, into space. This process disperses iron and other elements throughout the universe, eventually leading to the formation of new stars and planets.


Where is iron made mostly from?

Iron is fused within a star's core. When sufficient iron has accumulated and it begins to fuse, the energy of that fusion is too great and the star explodes creating all the heavier elements.up ya bum


Why do stars cool when the fusion cycle gets to iron?

Unlike lighter elements, fusing iron consumes more energy than it produces. This does not, however, cause a star to cool. Once a star gets to the point of fusing iron, the core stops producing energy and without the pressure from the heat it produces, the core collapses while the rest of the star is blasted away in an explosion.
