WebWhite dwarfs are the left over cores of dead solar mass stars. They are comprised mostly of atoms of oxygen and carbon created by the fusion of hydrogen and helium in the stars. The surface temperature of these stars is approximately 20,000°K. This heat is from the left over heat of the fusion processes in the old core. WebRed dwarfs are the coolest main-sequence stars, with a spectral type of M and a surface temperature of about 2,000–3,500 K.
