After going nova some stars turn into neutron star - being composed almost entirely of neutrons. These are very compact and massive and rotate extremely quickly. Typically the magnetic poles of the neutron star do not correspond to the rotational poles so the stars has a rotating magnetic field which is one of the conditions you need to produce radio waves. The radio waves produce by this situation is a beam of radio waves from the star's poles. As this beam sweeps out a cone there are times when it is pointed towards a potential observer and times when it is not. The pulses are the times when the beam flashes over the observer.
Pulsars are located every where around the universe keep in mind pulsars are neutron stars so that means they were formed by large stars that have aged and died out

The collapse of massive stars - the same as neutron stars.
Yes. All pulsars and neutron stars are the remnants of a supernova explosion.
Because I am interested in neutron stars.

Pulsars are not only a kind of neutron star, they are neutron stars. See related question.
The short length of pulsar pulses eliminate normal stars as possible pulsars because normal stars do not have strong enough magnetic fields.
Pulsars and neutron stars are hot because of all the residual heat left over in the core of the original star.
Pulsars --------------------------------------------Correction Pulsars are neutron stars that emit pulsating EM radiation at predictable frequencies. Obviously neutrons stars (something massive stars can collapse into when they die) are not the elementary particles of the universe. Therefore, 'quarks'.
No. It does not have enough mass. Only stars 8 times the mass of the sun or greater can become pulsars. The sun will become a white dwarf.
