Young stars are newly formed stars, often bright and hot, that are still in the early stages of their life cycle. Old stars are stars that have aged and passed the main sequence phase, becoming cooler and larger. Dead stars refer to objects that were once stars but have reached the end of their life cycle, such as white dwarfs, neutron stars, or black holes.
A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar spins. When those beams flash over Earth, we see them as regular, repeating pulses of radio emission.
Yes, the mass of a young star is typically more than that of a dead star. Young stars are actively fusing hydrogen into helium in their cores, generating energy and maintaining their mass. Dead stars, such as white dwarfs or neutron stars, have already exhausted their nuclear fuel and are no longer undergoing fusion processes, resulting in lower mass compared to when they were actively burning fuel.
Scientists know that elliptical galaxies do not contain many young stars because observations have shown that they have mostly older stars with low levels of interstellar gas and dust needed for star formation. This lack of gas and dust suggests that these galaxies have exhausted their supply of materials for forming new stars and are no longer actively forming young stars.
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.
All young neutron stars in reality are "pulsars". However, for a neutron star to be termed a pulsar, it's magnetic axis has to point towards Earth. (So we can see the pulse, even though all young neutron stars have a pulse, they cannot be observed from Earth.)

All young neutron stars spin rapidly. You might be confused with a pulsar. See related questions.
An AXP, an anomalous X-ray pulsar, is another name for what is now widely believed to be magnetars - young, highly magnetized, neutron stars.
No. A neutron star ts the remnant of a massive star that exploded.
You are describing a pulsar, which is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation along its magnetic poles. These beams of radiation sweep across space as the star rotates, causing the observed pulsating light.

(Quotation from "The Young Oxford Book of Astronomy" Simon and Jacqueline Mitton)"In the intense Magnetic Field of a Neutron star, spiraling electrons generate radio waves that are beamed out like a searchlight. The star spins rapidly, swinging the radio beam across our line of sight, like a lighthouse. Some Pulsars emit light, X-rays and gamma rays as well as Radio waves. The slowest pulsars have pulses about four seconds apart but the most rapid repeat in a matter of milliseconds."Which basically tells you that neutron stars can be pulsars, and the pulsar is not an individual part of a neutron star.
young
Yes, there are young stars in the Milky Way Galaxy.
neutron star is a stellar remnant so it is neither a young star nor an old star . It is formed by the gravitational collapse of massive star and are composed of neutrons . neutron star has a mass in between 1.35 to 2 solar masses
