Rigel
Rigel pulsates. The color of this star is bluish-white, hotter than a star with a yellow color. It will use its energy quickly. The Sun uses the same gases as Rigel; hydrogen and helium make it shine. When Rigel loses its fuel inside the very hot core, it will blow up into the red supergiant stage of its life and explode in a supernova. A black hole or a neutron star might be left.
