O star | O, B, A, and early F | 35000 K | very high | blue-white | He II | rare | 3 to 6 million years | early star | Very hot blue star, whose spectra is dominated by the lines of singly ionized helium (see Pickering series). (Most other lines are from at least doubly ionized elements, though H and He I lines are also present.) O stars are useful because they are found in dust clouds and virtually define the spiral arms. | |||
Mintaka | O9.5II | Orion | 35000 K | bright giant | very high | blue-white | He II | rare | 3 to 6 million years | One of the three stars in Orion's belt, and the star along whose line of sight interstellar gas was first spectroscopically detected. | II |
