This means that on a HR diagram, a star's size is easy to read off once its luminosity and color are known. The HR diagram is a key tool in tracing the evolution of stars. Stars begin their life on the main sequence, but then evolve off into red giant phase and supergiant phase before dying as white dwarfs or some more violent endpoint.
