What is the name to neutron stars that give off pulses of radio waves?

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.

∙ 12y agoAll young neutron stars give off electromagnetic radiation. If that radiation is directed towards Earth it is called a pulsar.
So ONLY if that radiation is directed towards Earth is it called a pulsar, but they are the same thing.

The light they emit from the magnetic poles is continuous, but as that pole is spun around relative to the rotational axis, the beam of energy is swept around like a lighthouse on Steroids. Some Pulsars have been measured spinning 900 times per second - close to the theoretical maximum.
Technically, all newly formed neutron stars emit a beam of electromagnetic radiation. It's only if this "beam" is pointed towards Earth and can be observed is it called a pulsar.

What is a highly magnetize rotating neutron stars I met a beam electromagnetic radiation in the form of radio waves?
A pulsar
What special name is given to spinning stars that transmit radio waves?
Pulsars
What do neutron stars emit?
If a neutron star's rotational period is fast enough to produce jets (A pulsar), said jets will emit radio waves, with faster periods emitting higher frequency radiation as well as the jets themselves emitting synchrotron radiation. Also, unless the neutron star were 0K, it will emit thermal radiation However, as far as a neutron star that isn't a pulsar, nobody knows if they emit anything but thermal radiation.
How can radio waves be used to observe stars?
1) Any object that emits radiation (because of its temperature) will emit in all wavelengths, including visible light, infrared, radio waves, ultra-violet, etc.What changes is the proportion of each (which depends directly on the temperature).2) The Earth's atmosphere is transparent to radio waves (meaning: it is easy to receive radio waves from space -- in general they are not blocked by the atmosphere).3) It is easy to build a receiver that gives us the direction from which the radio waves are coming. We can draw maps of radio sources (the same way that taking pictures in visible light lets us draw maps of the visible stars).

What type of star gives out regular pulses of radio waves?
Pulsars. They are very dense neutron stars that rotate quickly and very regularly, emitting radiation pulses towards the earth like a lighthouse.
A word meaning a place in space where radio waves are emitted?
Pulsar - Astronomy . one of several hundred known celestial objects, generally believed to be rapidly rotating neutron stars, that emit pulses of radiation, especially radio waves, with a high degree of regularity.
Do neutron stars have pulsars?
(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.
Why do some stars turn into pulsars?
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.

What do gammarays have to do with the universe?
gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwaves and radio waves are all part of the electromagnetic spectrum. All these waves are released by different bodies in space. Gamma rays and X-rays can come from Quasars, neutron stars. Radio waves can come from even simple radioactive bodies (very unlikely to be detected).
