Neutron+Stars(Pulsar)+1B

=NEUTRON STARS=
 * 20 km in diameter
 * The stars are very dense.
 * They range from 10-15km in radius.
 * Neutron stars form from burnt-out stars and they do not glow.
 * After stars burn nuclear fuel they will encounter a supernova explosion. Meaning neutron stars are the end of a stars life.
 * When the star collapses it causes the matter to be converted into mostly neutrons, therefore it is called a neutron star.
 * One of the few possible conclusions of stellar evolution. (the time in which it emits light and heat)
 * The heavier, the smaller.



=PULSARS=
 * Rotating neutron stars.
 * Releases beams of radiation.
 * Rotations of the neutron stars gives the "pulse" of the pulsar.
 * Highly magnetized

Three distinct classes of pulsars:

 * Rotation-powered pulsars**: star's loss of rotational energy powers radiation
 * Accretion-powered pulsars**: gravitational potential energy of accreted matter is the energy source that produce x-rays.
 * Magnetars**: where the decay of an extremely strong magnetic field powers the radiation.
