Dead Star

Description
A dead star is a star that has burnt out. This is extremely rare due to the fact that when a star exhausts all its hydrogen, it expands into a red giant and then becomes a white dwarf. However, by some unknown cause, occasionally a star will simply burn out. Theories believe that this may happen due to the star using nuclear fission to split the leftover helium atoms and burn out its helium, thus keeping it alive longer. However, when the star runs out of helium atoms, it simply becomes cold; a husk of the magnificent star it once was. Due to its vastly different properties, a dead star is not technically a star, but is still classified as one under the Ravium Star Classification system.
