Both are remainders of stars, that ran out of fuel. (So are white dwarves.)

Why do astronomers believe that pulsars are rapidly rotating neutron stars?

Astronomers believe that pulsars are rapidly rotating neutron stars because neutron stars are the only objects in the known universe that rotate that fast, and because pulsars are created by some sort of rapid movement.

What does a neutron star look like?

Nobody really knows. However we do know that is a spherical object - not an oblate spheroid - about the size of Manhattan (about 12km in diameter) with a very smooth surface. Smoother than anything on Earth.

A young one will be very hot, and it will have a massive gravitation density.

Why is minimum mass for an object to become a star?

The smallest known star is OGLE-TR-122b, a red dwarf star which has a radius of only around 12% of our suns mass, only about 20% bigger than the planet Jupiter (although it's mass is 100 times that of Jupiter). You could get smaller stars though in theory, nuclear fusion could be supported by stars of only 0.08 solar masses.

What happens when a neutron star dies?

A neutron star is already dead, in the sense that it no longer produces energy through fusion. It can only get colder and colder, as it radiates its residual energy out into space. If enough mass falls onto the neutron star, it may also convert to a black hole.

How much would a spoonful of a neutron star weigh?

A neutron star is so dense that one teaspoon (5 millilitres) of its material would have a mass over 5×1012 kg or 5,500,000,000 tons. About 900 pyramids of Giza.

The resulting force of gravity is so strong that if an object were to fall from just one meter high it would hit the surface of the neutron star at around 2,000 kilometres per second, or 4.3 million miles per hour.

What gives off, the injector pluse? Do you mean, where do the pluse signals, that trigger the injectors, come from? The EMC (engine managment computer) usually handles this, after receiving bizillions of sensor readings, from every related sensor, involved in the process.

Why will the sun never become a neutron star?

The Sun will never leave behind a stellar remnant such as a neutron star, as it does not have enough mass to achieve the massive pressures required to make one.

Our Sun will end up as a white dwarf stellar remnant.

What would happen if a neutron star landed on earth?

It would be the other way round: basically, the Earth would fall on the neutron star. Because of its much, much larger mass (about a million times larger than Earth), the neutron star would probably hardly be affected; but Earth would be utterly destroyed (and become part of the neutron star).

Why is a neutron star expected to spin rapidly?

Because of the angular momentum when it is formed causes it to spin so rapidly.

How is a neutron star formed?

The story begins when 1) an aging star swells to a red giant, and 2) it explodes in a Type II, Type Ib, or Type Ic supernova, then 3) it leaves behind a cooling core that forms the ultradense neutron star.

A link is provided to the Wikipedia article on the neutron star.

The mass of a star which is 1.4 to just under 3 times the mass of the sun provides a scenario where that star has used up its hydrogen fuel and the core begins to change the overabundance of helium into carbon then eventually into silicone and so on until the transference no longer produces energy which happens when the core goes to iron. Then the two forces that are constantly in conflict in the nature of stars becomes out of balance. Gravity is the winner and the thermonuclear forces begin to shut down. This is not a gradual process at the end. This is the same process that occurs in the death of any star. However, a star this big suddenly the whole core collapses in an actual instant. The outer layers of the star are blown off in a cataclysmic explosion. The gravity crushes the atoms which compose the core that did not blow off in the instantaneous explosion of its outer layers. This crushing gravity is not enough to cause a "Black Hole," but it is enough to make the electrons in the shell of those atoms combine with the protons in the nucleus of those atoms turning them into neutrons. The entire star with a diameter of well over a million to 3million miles reduces down to the diameter about the size of a city, maybe twenty miles across. The surface has the smoothness of a cue ball. On an object the diameter of a city there is hardly a bump even a millimeter high. These things spin at fantastic rates in some cases thousands of times a minute. This causes an electromagnetic emission which is focused at the poles of this spin and is intense in its strength. These signals can often be detected many light years away. This material that composes the neutron star, the size of a teaspoon might weigh 5,000 tons. All this leads to one of the most bizarre objects in our Universe.

What determines whether a supernova becomes a neutron star or a black hole?

The stars solar mass, or relative size to the sun. If its gravity is big enough, when it does condense in on itself, it will create a black hole. If not, it will form a highly dense clump of matter, or a Neutron Star If the stars mass is more than 3 solar masses, it will form a black hole. If it is less, it will form a neutron star

What would happen if your sun was replaced by a pulsar?

We would all be killed in the supernova explosion that created the pulsar out of our Sun. The Earth itself would be vaporized. Any returning space travelers would be fried by the intense pulses of gamma radiation that give the "pulsar" or "pulsing gamma ray source" its name.

However, this cannot happen - because our Sun isn't nearly massive enough to go supernova.

Are pulsars neutron stars?

When a neutron star is "born" [See related question], it emits a steady beam of electromagnetic radiation. When this beam is directed towards Earth it is called a Pulsar. [See related question]

See related link for a pictorial of the beam.

If the beam is not directed towards Earth, then it is only observed as a neutron star because we cannot detect the electromagnetic radiation beam.

As a neutron star slowly ages (10 -> 100 million years), this beam slowly "switches" off and the pulsar is no more.

So all neutron stars in their early stage, emit a steady beam of electromagnetic radiation, but it's only called a pulsar if it's directed towards Earth.
