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 neutron is call neutron?
The neutron is called the neutron because it it electrically neutral, hence the neu- prefix
What is the effect of slow neutron on nuclear reactions?
Because of neutron multiplication ratio.....
Which state of matter has highest density?
The singularity in a black hole, then comes the material in a neutron star.
Why is there an upper limit to the mass of neutron stars?
There is an upper limit to the mass of neutron stars because if the neutron star is too massive, neutrons would be crushed by the gravity of the neutron star, and the neutron star would collapse into a black hole.
How does nuclear fission end?
It ends by losing the critical mass or by introducing high neutron capturing material.
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.
What forms leftover material from a supernova?
neutron stars

What has less mass nuleus or neutron?
Neutron because it is part of the nucleus
What is the effect of slow neutron on nuclear reactions?
Because of neutron multiplication ratio.....
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.
Which state of matter has highest density?
The singularity in a black hole, then comes the material in a neutron star.
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
Why is there an upper limit to the mass of neutron stars?
There is an upper limit to the mass of neutron stars because if the neutron star is too massive, neutrons would be crushed by the gravity of the neutron star, and the neutron star would collapse into a black hole.
How can the rate of reaction be slowed down in a nuclear fission reactor?
By inserting the control rods which absorb neutrons using boron, cadmium, or other material with a large neutron capture crosssection. If the reactor should begin to run out of control the SCRAM system will suddenly insert large amounts of neutron absorbing material, instantly stopping the neutron chain reaction.
