No. Pulsars are a result of stars that have gone supernova, leaving behind a rapidly spinning neutron star. The neutron star produces the phenomenon known as a pulsar, which is a beam of electromagnetic energy that radiates from the star. The name "pulsar" is derived from the fact that we can only "see" the radiation when the beam is pointing towards the earth, which happens in intervals as the neutron star rotates, making it seem as though it is pulsating. This is also known as the "lighthouse effect".
No. A pulsar is a neutron star.

False. A pulsar is not a white dwarf; it is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation. Pulsars are the remnants of supernova explosions, while white dwarfs are the remnants of low to medium-mass stars that have exhausted their nuclear fuel and shed their outer layers.
Pulsar
The density of a pulsar or neutron star is much greater than that of a white dwarf. A typical (if there is such a thing) neutron star has a density of between 8.4 × 1016 to 1 × 1018 kg/m3 whereas a white dwarf has a density of about 1 × 109 kg/m3
I think that's a pulsar.
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
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.
A pulsar is a type of neutron star, a collapsed core of an extremely massive star that exploded in a supernova. Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
Is it a pulsar, a G2 star, a supergiant or a white dwarf? Please answer one of the following.
