Nuetron+Stars+4B

=__Introduction to Neutron Stars__= ==The smaller a Nuetron star becomes, the heavier it gets. The Nuetron star is also 1.4 in mass, and 3 times heavier then our sun. Neutron stars are the endpoint of a massive star's life. A typical Neutron star can be the size of a small city. It's only 10 kilometers in diameter, but it could of had a mass of three suns. If you get a spoonful of Neutron star materials, on Earth it would weigh as much as all the cars together on Earth. A massive star's core would begin to fall under gravity when it doesen't have any more nuclear fuel in its core.==



==Neutron stars rotate very quickly following their creation because the conservation of angular momentum. The slow rotation of the original star's core speeds up as it shrinks. A newly created eutron star can rotate several times a second. The strongest megnetic fields produced on Earth would not be as strong as the Neutron star magnetic fields because its magnetic fields can be a million times stronger.==



This diagram above shows a pulsar and the rotation axis and the magnetic axis.
==Jocelyn Bell Burnell who is a graduate student discovered pulsar in the late 1967 as radio sources that flashes on and off at a constantly frequency. Pulsars are rotating neutron stars that contain jets of particles moving almost like the speed of light flowing out above their magnetic poles. These jets can produce a very powerful beams of light.==



This image (left) was taken by a ROSAT satellite image of NASA. It shows a x- ray image of a supernova remnant and its central neutron star.
==The supernova remnant, which is also known as Puppis A, is estimate about 6000 light years away. It is also known as one of the brighter x-ray and radio sources in the sky. The remains of the supernova remnant glows with diffuse x-rays, but there is a brighter point x-ray source close to the center of the image (yellow highlighted in the blowup). This is almost certainly the neutron star that was produced in the supernova explosion.==
