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.
Yes. A pulsar is a rapidly spinning neutron star.
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.
A pulsar is a rapidly spinning neutron star that releases regular pulses of electromagnetic radiation from its magnetic field

A pulsar is a rapidly-spinning neutron star, the remains of a supernova explosion.
A rapidly revolving item is called a "spinning" object. Examples include a spinning top, carousel, or rotating blade.
neutron star has been observed at the center of a supernova remnant, known as the Crab Nebula. This neutron star, also called a pulsar, spins rapidly, emitting beams of radiation that are observed as pulses by astronomers.
"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
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.
The fastest spinning neutron star that we've found so far is XTE J1739-285, which spins 1122 times every second. It was found by NASA's Rossi X-Ray Timing Explorer (RXTE) satellite. The most rapidly spinning pulsar, however, remains PSR J1748 2446ad, which spins 716 times a second. This pulsar was found by a team at Montreal's McGill University.
If it also emits pulses in each rotation, it is called a pulsar.
because of the great mass of the star, the gravity of it is very high. So after its death, it actually contracts so tightly that even protons and electrons combine to form neutron and thus results to a star called neutron star. If its previous mass is considerably low, then it could have become a white dwarf
