A supernova occurs when a high mass star dies and becomes a neutron star. As the core collapses because fusion burns out and radiation pressure can no longer hold it up, then degenerate electron pressure can not hold it up, the electrons are forced into the nucleus and combine with protons to form neutrons, the strong force causes the nuclei to merge into one ball of neutrons: a neutron star. The surface of the neutron star is very hard and as additional matter from the original star continues to fall in and merge into the neutron star, a "traffic jam" occurs and the shockwave resulting from this reflects off the super hard surface of the neutron star, driving the supernova explosion. Suddenly everything falling in is now rushing out. This can only occur once.

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.
Will Sirius become a supernova?
No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.
What Materials in the core of a supernova?
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
What kind of star is most likely to become a white-dwarf supernova?
A supernova is a star that has exploded into dust and gas. A white-dwarf is a small, hot, dense star nearing the end of its life, that did not have enough mass to go supernova. So the answer is "none".
What causes a giant star to turn into a white dwarf?
A giant star would experience a supernova explosion, in order to become a white dwarf.
Could a supernova on Jupiter cause the earth to be pushed off it axis?
Only a very, very few stars have mass enough to become supernova. Jupiter is a planet not a star. It is far to small to become a star, let alone 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 happens to a burnt out star?
If it's a big enough explosion it will become a supernova
Will a very large star go through several supernova explosions in its lifetime?
A star will become a supernova only once.However, a white dwarf can have multiple novaeruptions.See related questions
What a star may become after a supernova explosion?
Usually a neutron star, or a black hole, depending on the remaining mass.
What 2 things can happen to a star after a supernova?
It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser black hole.
What can happen when stars collide?
They form a new star, or the might become a supernova......ouch
Will Sirius become a supernova?
No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.
What are the types of stars a high mass star can become after it goes supernova?
Once a high mass star goes supernova, it doesn't become any other type of star - it becomes a pile of enormously dense stellar ash, or if it was big enough to begin with, it becomes a black hole.
Why do all stars end in a supernova?
Oops! Not all stars end up as a supernova. To become a Type 2 supernova, the star has to be between 8 and 50 times larger than the Sun.
When was Rock Star Supernova created?
Rock Star Supernova was created in 2006.
What Materials in the core of a supernova?
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
