The material that accretes onto a neutron star or black hole is expected to emit x-rays because?
Accretion disks generally are energetic because of gravitational compression of infalling matter, and frictional forces which heat the matter in the accretion disk. The frequency depends on the mass of the central body. Protostellar accretion disks emit in the infrared, the higher speed and friction associated with the more intense gravity of neutron stars and black holes cause them to radiate in the higher x-ray frequencies of the electromagnetic spectrum.

Why do you expect neutron stars to have a powerful magnetic field?
Neutron stars are expected to have strong magnetic fields because they are formed from the collapsed cores of massive stars, which inherently had strong magnetic fields. As the core collapses, conservation of magnetic flux leads to an intense magnetic field in the neutron star. Additionally, the rapid rotation of neutron stars can amplify their magnetic fields through processes like dynamo action.
Why do you not expect to find a 5 solar mass neutron star?
There are no neutron stars with 5 solar masses because one if a neutron star exceeds 3 solar masses, the neutrons inside would no longer be able to support the extreme gravity, so the neutron star would then collapse into a black hole.A neutron star is prevented from further collapse by a force call neutron degeneracy pressure. Above 3 solar masses gravity will overcome this force and the stellar remnant will collapse completely to form a black hole.
Which state of matter has highest density?
The singularity in a black hole, then comes the material in a neutron star.
How much does 1 cubic centimeter of neutron star stuff weigh in tons?
1,100,000,000,000 kilograms = 1.21254244 × 109 short tons
What forms from the leftover material from a supernova and it may contain as much as three times the mass of the sun?
Neutron star
Why is a neutron star expected to spin rapidly?
All young neutron stars spin rapidly. You might be confused with a pulsar. See related questions.
How heavy is a teaspoon of a neutron star?
A teaspoon of material from a neutron star would weigh about 6 billion tons.

What has less mass nuleus or neutron?
Neutron because it is part of the nucleus
Will Betelgeuse become a neutron star?
After a supernova explosion in Betelgeuse it will definitely become at least a neutron star. However, because of it's mass it's more than likely to become a black hole. If it does, then it will be the closest black hole to Earth.
What is the fastest sound can go?
Probably very fast indeed if one considers things like nuclear matter or the quark soup expected from the LHC or the material of a neutron star... The sums get a bit difficult though. It'll be a big fraction of the speed of light.
Can a neutron star or a pulsar become a black hole?
No, they cannot.A neutron star forms when the core of a supernova is halted by rising neutron pressure (due to the increase in the density of the core). If this central core ends up having a mass greater than three solar masses, it will end up forming a black hole instead of a neutron star. A pulsar is a type of neutron star that rotates and is highly magnetized.As such, since they are not massive enough to form a black hole in the first place, they probably won't ever become one. The only way that they could possibly become a black hole after formation is if they collide with another neutron star or black hole.
What would happen if a teaspoon of neutron star material were to come into contact with Earth?
If a teaspoon of neutron star material were to come into contact with Earth, it would release an immense amount of energy, potentially causing catastrophic damage. The extreme density and gravitational pull of neutron star material would likely result in a powerful explosion upon impact, leading to widespread destruction in the surrounding area.
What forms leftover material from a supernova?
The leftover material from a supernova explosion forms either a neutron star or a black hole, depending on the mass of the collapsing core. A neutron star is extremely dense and composed mostly of neutrons, while a black hole is a region of spacetime where gravity is so strong that not even light can escape.

What contained the densest material in the universe?
as neutrons have heaviest mass in an atom,and also neutrons are major constituents of neutron stars.so neutron stars ae most densest in the universe
