What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
A massive stars terminate in a brilliant explosion called a?
it is Supernova
What is a dead star with the density of an atomic nuclei called?
A dead star with the density of an atomic nuclei is called a neutron star. Neutron stars are incredibly dense and are composed mostly of tightly packed neutrons. They form when massive stars explode in a supernova and their cores collapse under gravity.
How is a supernova formed and what are the key processes involved in its creation?
A supernova is formed when a massive star runs out of fuel and collapses under its own gravity. The key processes involved in its creation include the fusion of elements in the star's core, the buildup of iron, and the sudden collapse and explosion of the star's outer layers. This explosion releases a tremendous amount of energy and creates a bright, expanding shell of gas and dust.
What is the final stage of super giant stars?
The final stage of supergiant stars is a supernova explosion. When these massive stars exhaust their nuclear fuel, they can no longer support their own gravity, leading to a catastrophic collapse of the core. This collapse results in a rebound effect that expels the outer layers, creating a bright and powerful explosion. Depending on the mass of the original star, the remnant can become a neutron star or a black hole.
What is the estimated number of nutrinos released by the collapse of a supernova?
There are about 40 to 50 of neutrinos released by the collapse of a supernova. This is known as a massive star.
If a star is massive enough what can result after it produces a supernova?
If a star is massive enough, after it produces a supernova it can either leave behind a neutron star or collapse into a black hole, depending on the mass of the original star.
What will most massive stars form?
Most massive stars will eventually form black holes after they go through their life cycle of burning through their nuclear fuel, leading to a supernova explosion. The remnants of the supernova collapse into a dense core, which, if above a certain mass threshold, will become a black hole due to the force of gravity overwhelming other forces.
In the last stage of stellar evolution following a supernova stars too massive to form neutron stars may form a?
In the last stage of stellar evolution, stars too massive to form neutron stars may collapse into black holes following a supernova explosion. When these massive stars exhaust their nuclear fuel, their cores collapse under gravity, leading to an event horizon that characterizes a black hole. The outer layers are expelled during the supernova, while the core's collapse results in an incredibly dense singularity from which nothing, not even light, can escape. This process marks the end of the star's life cycle, transitioning it into a black hole.
How long does it take for the core of a massive star to collapse once fusion ceases?
Once fusion ceases in a massive star, it takes only a few seconds for the core to collapse and undergo a supernova explosion.
What type of supernova will Betelgeuse be?
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
Why won't our Sun end in a Supernova explosion?
Our Sun is not massive enough to end in a supernova explosion. When it nears the end of its life, it will shed its outer layers as a planetary nebula and eventually collapse into a white dwarf. Supernova explosions typically occur in massive stars that have exhausted their nuclear fuel and undergo a catastrophic collapse.
What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
A black hole is the remains of a supermassive star after a supernova?
Close. A black hole is formed when a massive star runs out of fuel and collapses under its own gravity, compressing its mass into an infinitely dense point called a singularity. This collapse can occur after a supernova explosion in the case of a massive star, or through other processes such as the direct collapse of gas in the early universe for supermassive black holes.
After a supernova the stellar core may remain as a?
After a supernova, the stellar core may remain as a neutron star or, for more massive stars, collapse into a black hole. Neutron stars are extremely dense, composed almost entirely of neutrons, while black holes have such strong gravity that not even light can escape from them.
How stars go supernova?
Massive stars. See related question: 2nd Answer: Yes, massive stars, but ones with another star like a red giant orbiting each other. The to-be supernova 'sucks' material from the other star near it until its mass is large enough to make the star collapse and burst.
Does a supernova implode or explode to form a black hole?
It depends on the mass of the star. When massive stars die the result is usually an enormous explosion called a supernova, but the core will collapse to form a dense remnant. If the remnant is less than 3 times the mass of the sun then it will form a neutron star. If it is greater than 3 times the mass of the sun it will form a black hole. Extremely massive stars may collapse directly into a black hole with no supernova.
