B star O, B, A, and early F 11000 to 28000 K blue-white He I early star Blue-white star of spectral type B whose spectra are characterized by absorption lines of neutral helium which reach their maximum intensity at B2. The Balmer lines of hydrogen are strong, and lines of singly ionized oxygen and other gases are also present.

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

subgiant greater than 1000 Kelvin star A star whose position on the H-R diagram is intermediate between that of main-sequence stars and normal giants of the same spectral type. IV
