What would happen to a neutron star with an accretion disk orbiting in a direction opposite to the neutron star's spin?
The neutron star so affected wouldn't really notice. The mass of the neutron star is huge compared to that of the material in the accretion disk. And that matter, when it falls in, wouldn't really "slow" the spin of the star much unless there was a gigantic quantity of matter falling in and/or it acted over a very long period.
Is a pulsar a white dwarf?
A pulsar is a type of neutron star, a collapsed core of an extremely massive star that exploded in a supernova. Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
Describe the further rearrangement of atoms in the neutron star?
The neutron star hasn't atoms.
How did neutron stars get its name?
The name "neutron star" some from the fact that the neutron star is mainly composed of neutrons. The gravitational pull of a neutron star is so strong that most matter are crushed into neutrons.
How hot is a pulsar?
A Pulsar is nothing more than a neutron star which points towards Earth [See related question] A newly formed neutron star would have a temperature of 1011 - 1012 Kelvin, but after a year, it will cool down to 106 (a million) Kelvin, due to the large number of neutrinos it emits.
Why does theory predict that a neutron star should spin fast?
Neutron stars are born from massive stars collapsing, which conserves the original star's angular momentum. Since the original star had a slow rotation, the neutron star that forms from it will have a faster spin due to the conservation of angular momentum.
Is a pulsar a neutron star?
Yes. A pulsar is a rapidly spinning neutron star.
Why do neutron stars rotate so much more rapidly than ordinary stars?
Neutron stars rotate rapidly due to their conservation of angular momentum. When a massive star collapses into a neutron star, its core spins faster as it contracts. Since angular momentum is conserved, the neutron star continues to rotate rapidly as a remnant of the collapsed star.
What is spinning neutron star called?
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.
Why don't all supernova remnants contain pulsars?
A "pulsar" is a rapidly-rotating neutron star, with a core of collapsed matter. The pulsar rotates because the original star rotated. If\\ WHEN a massive star becomes a supernova, the force of the explosion will crush the core of the star into either a neutron star or a black hole, if the original star was massive enough. The angular momentum (the "spin energy") of the original star doesn't disappear; like a figure skater pulling in her arms to spin faster, the neutron star will spin more rapidly because it has collapsed in size. If the neutron star's axis is pointed somewhere close to Earth, we detect the pulsating x-rays and we call it a "pulsar". So to answer the question, all supernova remnants contain either neutron stars or black holes, but they are pulsars only if they spin rapidly.
What is A rapidly spinning neutron is called?
A young neutron star. Really - that is what a neutron star is. If the neutron star's magnetic field is pointed towards Earth, then it is referred to as a pulsar - because of it's rapid pulsations [See related question] but it is still a neutron star.
Why do neutron star spin so rapidly?
Most stars spin (albeit is very slowly), but when the star starts to shrink it will speed up due to conservation of angular momentum. Moreover because a neutron star is so very heavy it takes a long time for it to slow down (breaking can occur via magnetic fields for example). You can test this principle yourself by sitting into an office chair, spreading your arms, and have someone give you a good whirl. You will find that while spinning you will spin faster if you pull your arms inwards and slower if you put them out again.
Why do pulsar stars spin?
Pulsar stars spin because they are formed from the collapsed core of a massive star that has exploded in a supernova. During the collapse, the core's rotation becomes faster due to the conservation of angular momentum. This rapid rotation causes the neutron star to spin rapidly, emitting beams of radiation that we detect as pulses from Earth.

How are neutron stars related to pulsars?
A pulsar is a rapidly spinning neutron star that releases regular pulses of electromagnetic radiation from its magnetic field
How are pulsars formed?
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic energy. Neutron stars form when the core of a massive star collapses and goes supernova leaving behind a neutron star which will begin rotating and releasing energy.
