A star O, B, A, and early F 10000 K white H I early star Star with spectral type A in which the spectrum of the Balmer lines of hydrogen attain their greatest strength. Helium lines can no longer be seen. Some metallic lines are present; in late A stars the H and K lines of ionized calcium appear. A0 stars have a color index of zero.

dwarf greater than 1000 Kelvin d star main sequence star Star with mass equal to or less than that of the sun. More generally, any star on or below the main sequence in the Hertzprung-Russell diagram. V

naked eye star Milky Way greater than 1000 Kelvin for many centuries asterism naked eye object brighter than 5 A star visible without visual aids
