What are two possible results of a supernova explosion?
The core of the star can collapse to form a neutron star or a black hole. The outer layers of the star can be ejected into space, enriching the surrounding interstellar medium with heavy elements.
What happens when a massive star cools and collapses?
Massive stars do not cool as they collapse, the collapse in on themselves because their cores become too heavy and dense, these atoms in the core are in an area so dense and so hot that it continues to increase its temperature as it explodes.
What is a region in space which is left behind after a major star dies?
A region left behind after a major star dies is called a supernova remnant. Supernova remnants are expanding shells of gas and dust that result from the explosive death of a massive star in a supernova event. They play a crucial role in enriching the interstellar medium with heavy elements and triggering new star formation.
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.
What force makes a red super giant collapse?
a strong gravitational force which means that the star will collapse in on itself
If a star dies what happens?
it depends on the mass. If the star is small and it dies then it will turn into a red giant then a white dwarf. But if the star has enough mass and is bigger than any other star then it will collapse and turn into a black hole.
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.
Does nuclear fusion occurs as stars cool down?
The star will continue to fuse hydrogen until it runs out of resources and dies out, after which it will collapse and die.
What element does a star run out of that causes them to die?
A star dies when it runs out of fuel to sustain nuclear fusion in its core. This fuel is mainly hydrogen, which gets converted into helium through nuclear fusion. Once the star runs out of hydrogen, it will expand and eventually collapse, leading to its death in a supernova explosion.
What causes the collapse of a star?
The collapse of a star is based on its age. When it runs out of "Fuel" its inside contracts as the outside expands. it can then super nova or collapse into a tiny star.
What conditions of a Supernova cause elements that are heavier that iron to form?
The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.
Were did a black hole come from?
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole
Why can only very massive stars form a black hole?
When a star dies the core collapses, but in most cases collapse stops at the level of either a white dwarf or a neutron star. The internal pressure of the remnant core is enough to stop further collapse. Only the most massive stars have strong enough gravity to overcome these forces and collapse into black holes.
What is left behind after a star with four masses has died?
After a star with four solar masses dies, it can collapse and form either a neutron star or a black hole, depending on how much material is left behind after the explosion during its death throes.
What are two possible results of a supernova explosion?
The core of the star can collapse to form a neutron star or a black hole. The outer layers of the star can be ejected into space, enriching the surrounding interstellar medium with heavy elements.
When a red gaint complets helium fusion and collapses it becomes?
When a star runs out of helium, it may still fuse helium into heavier elements - it need not collapse immediately. Eventually, however, the star will run out of usable fuel, and collapse. In that case, depending on its remaining mass, it will become a white dwarf, a neutron star, or a black hole.
What happens when a massive star cools and collapses?
Massive stars do not cool as they collapse, the collapse in on themselves because their cores become too heavy and dense, these atoms in the core are in an area so dense and so hot that it continues to increase its temperature as it explodes.
