Notes:

  1. The sources for this table are SEDS (Students Explore the Universe) and Se-605. The only numbers from Se-605 are the absolute magnitudes: they are somewhat out of date, but no matter here.

  2. There is such a thing as luminosity class indicated by a Roman numeral after spectral type. Main sequence stars are luminosity class V. Only main sequence stars For other special symbols accompanying spectral type consult SEDS.

  3. You can see that stars are bright because they have either high luminosity (i.e., low absolute magnitude) or because they are close. Star density in space decreases with increasing luminosity, and so, in fact, stars both very luminous and close are rare. Depending on how you count these things, Canopus may be the only such star. One can see that apparent brightness is NOT a good guide to relative distance.
