A pulsar. Neutron stars that are spinning rapidly can generate pulses of X-ray radiation, and are called "pulsars".
Interestingly enough, the first discoveries of pulsars were termed "LGM objects", for "little green men"; before the structure was understood, scientists thought that the PRECISELY timed pulses of X-rays might have been some sort of interstellar radio beacons, a galactic electronic navigational aid.
It is a neutron star. A pulsar is nothing more than a neutron star whose "beams" are detectable from Earth. Apart from that they are the same thing.
Good sentence for neutron star - WOW ! see that;s a neutron star !!
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.

The same size as a normal neutron star. See related question.
The average density of a neutron star with the same mass as the sun would be about 1 x 10^17 kg/m^3. Neutron stars are incredibly dense objects, as they are formed from the remnants of massive stars that have undergone supernova explosions.
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
No. A neutron star ts the remnant of a massive star that exploded.

A neutron star is a stellar remnant
No. Neutron stars are far MORE DENSE than the Sun's core. If the Sun were twice its actual mass, and if it were to collapse into a ball around 10 miles in diameter, THEN it would be as dense as a neutron star. Compared to a neutron star, the Sun is like a mist of hydrogen, a sort of fog.
Yes, both black holes and neutron stars are remnants of the death of massive stars. Neutron stars form when the core of a massive star collapses but does not produce a black hole. Black holes are formed when the core of a massive star collapses beyond the neutron star stage.
