Magnetic O stars
The printed version of the Magnetic O stars is very confusing because There is a ? Symbol which doesn’t make sense — Preceding unsigned comment added by 98.47.226.110 (talk) 03:10, 6 April 2022 (UTC)
 * The question mark is intentional. It is the symbol indicating this particular spectral peculiarity, although you don't see it very often.  Not a good choice IMO, but not many good symbols left.  Lithopsian (talk) 10:38, 6 April 2022 (UTC)

Percentages don't add up
In the table of proportion of main sequence stars by spectral class, the percentages don't add up to rather more than 100%! Steve (talk) 14:47, 8 June 2023 (UTC)
 * The numbers are calculated from table 2 in the given reference based on the total number of stars in each class compared to the total column. However, the number of stars in each class don't add up to the total 800.  I rebased the proportions on the actual total of 824 (and a fraction).  I'll expand the explanatory note to cover this.  There are some other sources that could be used (eg ), but I haven't found a peer-reviewed one.  The numbers don't end up radically different, and they actually vary quite a lot depending on how the sample is chosen.  Lithopsian (talk) 15:54, 8 June 2023 (UTC)

Diagram
The classification table is wrong by a mile! According to it, Kepler-186 is ~K8, AU Microscopii is K9 or M0, Canopus is F0, 2-MASS J0523-1403 is a brown dwarf, and Kepler-442 is ~M1 by radius. Please fix! Jtadesse (talk) 17:29, 28 November 2023 (UTC)
