Pulsars

What is it? Pulsar is a rotating neutron star that have jet particles spinning at the speed of light above the magnetic parts of the poles. the jets provide a very powerful light. the magnetic and rotational axis of a pulsar are not in a line (similar to earths) this makes the light from the jet go around the pulsar as the pulsar itself rotates. just like ships see lights in the ocean flash on and off people who look at pulsars see the same thing in the universe. They were discovered in 1967 by a Woman called Jocelyn Bell Burnel. She called it radio sources that gives of on and off frequency. Einstein had an x-ray of the nebula 'crab' this was observed in 1054 Ad the nebula surrounded the pulsar in both on and off states. this in when the pulsar was within the nebula and the pulsar was giving light, an easy way to say this is the pulsar was on here you cannot see the light of the pulsar therefore it is off.

A different type of pulsar can be seen by x-ray telescopes. when a neutron star has a strong gravitational pull on a normal star it starts to pull in the materials of the normal star the materials go into the magnetic poles when this happens it is called a accretion. after that the materials from the normal star becomes hot and gives off x-ray lights. The x-ray pulses can be seen when the neutron star is still hot and then it rotates through the line of sight from earth. these pulsars are called accretion powered pulsars, the normal pulsars are called spin powered pulsars they have different names to separate them from the normal and advanced.
