What element is stops the star from being able to burn?

Supernova Core Explosion: Once the silicon burning phase has produced an iron core the fate of the star is sealed. Since iron will not fuse to produce more energy, energy is lost by the productions of neutrinos through a variety of nuclear reactions.

What keeps a star burning?

Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.

What element is the stopping point for a star to stop and then die?

Helium burns to forge an even heavier mix of carbon, nitrogen and oxygen, and this renewed burst of energy puffs the star out into a vastly larger red giant. If the star is small enough, these heavier elements will never reach the burning point themselves and the fusion process will stop.

What happens when a star uses all of its hydrogen and helium?

Once a star has exhausted its supply of hydrogen in its core, leaving nothing but helium, the outward force created by fusion starts to decrease and the star can no longer maintain equilibrium. The force of gravity becomes greater than the force from internal pressure and the star begins to collapse.

Do stars burn hydrogen?

Stars on the main sequence burn by fusing hydrogen into helium. Therefore, large stars burn the hydrogen fuel in the core quickly, whereas, small stars burn it more slowly.

What elements do stars fuse?

After the hydrogen in the star’s core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and nickel requires an input of energy.

What do stars fuse after hydrogen?

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores.

Which stars burn out the fastest?

Heavier stars thus burn their fuel much faster than less massive ones do and are disproportionately brighter.
