Black Holes, White Dwarfs and Neutron Stars
« on: January 28, 2012, 05:53:00 PM »
In the stars like our Sun when the H and He fusion reaction finish, they become to White Dwarfs (degenerate electron stars).  These are cooling to their death, become to Black Dwarfs.

The stars with 1,4 to 3 mass of the Sun at the end of their life die exploding as Supernovas.  They left as residue a Neutron Star that we can observe like a Pulsar or cosmic beacon.  Their radiation comes to us like radio waves or also in the visible spectrum.

The most massive stars that at the end of their life have even more than 3 times the mass of the Sun collapse into Black Holes.
