WebMay 2, 2024 · But we don’t necessarily have to. If we can identify a star as main sequence, giant, or supergiant by the width of its spectral lines, we now have yet another simple, easy way to classify it: by the luminosity classes. The luminosity classes are as follows: Ⅰa − bright supergiant. Ib − supergiant. Ⅱ − bright giant.
