Luminosity Classification
A star's spectrum reveals not only its temperature but its size. The Yerkes system adds a luminosity class — from I for supergiants down through III for giants, V for main-sequence dwarfs, to VII for white dwarfs — to the Harvard spectral type. Together they place a star precisely: the Sun, for instance, is a G2V dwarf.
