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. | |||||||||||
