What causes X-rays to come out of an X-ray pulsar?

A pulsar is a neutron star. The electromagnetic radiation emitted by these stelar remnants is fairly tightly focused into beams by the very strong magnetic fields. So, as the neutron star rotates, this beam of light sweeps across the sky much like the beam of light emitted by a lighthouse. When such a beam sweeps past us we see a pulse of light. The light from a pulsar usually ranges from radio frequencies to the visible spectrum. X-rays are much short and, therefore, much higher energy forms of radiation. How it is that a pulsar could produce electromagnetic radiation that is so high in energy is something that we haven't figured out yet. Normally, we are not supposed to answer a question here with I don't know, but in this case, that is the only answer you are going to get. We don't know what generates these x-rays. We are still trying to figure that one out. ***************** "ella_D_sinnah: NOT USEFUL ACTUALLY... what kind of information is this????" It's telling you that we don't know what causes x-ray pulsars. If you have an answer, then I am sure that the astronomical community would like to here it.

A pulsar is the term applied to a stellar body or bodies that emit a pulsating electro magnetic spectrum. The fact that it pulsates suggests it is acutually two stellar bodies rotating around one another.

X-rays are part of the electromagnetic spectrum, more commonly known as light. this spectrum ranges from the longer wavelengths of light to the shortest in this order: Radio waves, Microwaves, Infrared, Visible, Ultraviolet, X-ray, and Gamma ray. ALL STARS AND ESPECIALLY PULSARS EMIT X-RAY LIGHT.
