What is the difference between a neutron star, a white dwarf, a brown dwarf, a red giant, a supernova?

Ok, I'll try and put this in simple terms...A Neutron star is made up entirely (almost) of neutrons, containing roughly or as much mass as our Sun but packed into a sphere only about 10km across. A white dwarf is what is produced when a low to medium mass star dies. They become red-giants during their helium-burning process after-which they shed their outer layers and become planetary nebulas. When its degeneracy pressure is exceeded the limit to which it cannot support this mass it may explode into a supernova. Now, a neutron star (as mentioned before), is the remnants of a supernova explosion. As for a brown dwarf they are failed stars that never heated up enough to explode into a normal star. Here's it all in a more scientific manner.. http://www.geocities.com/tonylance/dwarf.html May 17 05, 9:59 PM

yah, there different stages that a star may take in it's lifetime. This is coming my science classroom which i am currently in. May 18 05, 10:49 AM
