File:Morgan-Keenan spectral classification.png


Image depicting the Morgan-Keenan-Kellman spectral classification of main-sequence stars (1943). Sizes taken from the table at the stellar classification article on the English Wikipedia.

Some notes:

  1. These are main sequence stars only.
  2. The "floor" is there so we can compare the amount and colour of light coming from each star. The light intensity isn't proportional (that'd be rather intense), but is somewhat related to the actual ones.
  3. Larger stars show more colour since these output a lot more on the invisible spectrum. I tried to convey this by making them less white in the middle.
  4. The star's smoothness and the floor reflection were aesthetic choices.
