In all probability - not that this scenario would happen - but the resulting combination of masses, would push the combined "stars" over the Chandrasekhar limit and a black hole would form.

Why may there be more pulsars then we observe?

A "pulsar" is a rapidly rotating neutron star. The pulses are pulses of X-rays or gamma rays that are radiated continuously, but which are only detectable when the beam is pointed at the Earth.It seems likely that there are a great number of rotating neutron stars that do not happen to point at the Earth. They would not, therefore, be detectable.


Is the main difference between a pulsar and a binary system that a pulsar is made up of two neutron stars and that a binary system is made of of two normal stars?

Not exactly, while a pulsar is a specific type of neutron star (that being a "spinning neutron star") and a binary system is a pair of stars orbiting each other, a pulsar does not need to be part of a binary system. It would be possible, however to have a binary system with one of the pair being a pulsar and the other a neutron star (assumed to be the non-spinning or "normal neutron star" variety).


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.


Are the corpses of stars that are small or medium to begin with?

The "corpses" of stars may be white dwarves, neutron stars, or black holes (and perhaps "quark stars", but this is still very speculative). In general, the least massive stars - which also tend to be smaller - will become white dwarves. These are much smaller than "active" stars, but much larger than neutron stars or black holes. The more massive the star, the SMALLER will the white dwarf be - due to the increased gravity. Our Sun has a diameter of 1.4 million kilometers; other stars can be several times smaller, or larger - but a white dwarf only has a diameter of a few thousand kilometers. More massive stars become neutron stars, which have a diameter of 20-30 km - and an immense density, similar to that of an atomic nucleus. The most massive stars end up as black holes. Here, the only "diameter" that can be observed from the outside is that of its event horizon, which is directly proportional to the black hole's mass. A black hole the mass of the Sun would have a Schwarzschild radius (the radius of its event horizon) of about 3 km; therefore its "diameter" would be about 6 km. A black hole a billion times the mass of the Sun would have a Schwarzschild radius of 3 billion kilometers.


What is bigger a black hole or a neutron star?

It all relates to what you define as big. A black hole is an infinite region in space with an infinite density. It's "event horizon" is not infinite. If you wish to categorise between size of a neutron star and a black hole's "event horizon", then a black hole is, in most cases larger - but there are micro black holes, which exhibit all the characteristics of a black hole but have a much smaller "event horizon". In the physical sense, everything is bigger than a black hole, but in a terminological sense (the event horizon) it would depend on the mass of the black hole.

What is a neutron star collision?

That would be a collission between two neutron stars. Since many stars are actually double stars, this can happen now and then.


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.

What would happen if a neutron star collided with earth?

It is extremely unlikely that a neutron star (or any star or planet) will collide with the Earth, so this is not something that you need to worry about, however, if a neutron star were to collide with the Earth, the Earth would be captured by the intense gravitational field of the neutron star, and would be absorbed by the star. Under sufficient pressure, electrons and protons will merge to form neutrons, and so the atomic matter of which the Earth is composed can be converted into pure neutrons.


What would happen if a constellation and another constellation collided?

That isn't possible because the stars in any one constellation are all at different distances from us, and each star is moving in its own direction. There's no connection among the stars in a constellation.


How are neutron stars formed?

Neutron stars are formed when stars with more than 8 times the mass of the Sun run out of fuel and explodes as a supernova. After the star explodes, the core of the star remains, the core would then become a neutron star or a black hole. If the core remain is less than 3 times the mass of the sun, it would become a neutron star.


What effect do neutron stars and pulsars have on Earth?

Hardly any - they are very far away. However, a supernova (which would come before a neutron star) could have catastrophic effects on Earth, if it were to happen in our neighborhood (up to a few thousand light years!).


Where do neutron stars form?

Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.

Why do some stars end up as neutron stars?

Some stars end up as neutron stars because they exploded as a supernova and leaves a dense core behind. The strong gravity of the core compresses itself until protons and electrons are crushed into neutrons, this forms a neutron star. If the core is too massive, it would collapse into a black hole.
