WebbSince the stars at the upper right are very luminous yet nonetheless have cool, reddish surfaces, astronomers call them red giants. Similarly, since the stars at the lower left are very dim yet also white-hot, they are called white dwarfs. We have met the white dwarfs already, in a theoretical way. Now let's see where the real ones come from.
