: CAN SOMEONE EXPLAIN A NEUTRON STAR TO ME. THANK YOU

Hey Bill, here's some info. When a star has undergone various stages of stellar evolution (red giant, super giants) the core of the star eventually becomes an isotope of Iron. Before this iron core, the contents of the core were held up by "electron degeneracy", which means that two atoms cannot occupy the same space because of their electron clouds. Anyway, the iron core is so dense that the electron clouds breaks down, and the star collapses until "neutron degeneracy" holds up the core. This collapse sparks off an enormous explosion callled a supernova that rips away the outer layers of the star. What is tiny core (about 10-20 km across) that is nothing but neutrons (all the electrons are absorbed by protons), hence a neutron star.

Sorry so long, but I had to review for my test over this stuff tomorrow! Hope that helped. :)
