WebOct 10, 2024 · Astronomers can only estimate the distances to these stars: The closest O-type star, Zeta (ζ) Ophiuchi, lies roughly 370 light-years away; the nearest Wolf-Rayet star belongs to the binary system ... WebGiant stars are also classified by B-type, O-type, etc., and there's also yellow and white giants. Blue giants are probably only O-type or B-type, but I'm not too sure about the colour spectrums yet. Giants have about 1.168x the luminosity of an equivalent non-giant main sequence star, and 3.3x the max dyson sphere radius.

They have temperatures in excess of 30,000 kelvin (K). Stars of this type have strong absorption lines of ionised helium, strong lines of other ionised elements, and hydrogen and neutral helium lines … See more O-type stars are classified by the relative strength of certain spectral lines. The key lines are the prominent He lines at 454.1 nm and 420.0 nm, which vary from very weak at O9.5 to very strong in O2–O7, and the He lines at 447.1 nm … See more O-type stars are rare but luminous, so they are easy to detect and there are a number of naked eye examples. Main-sequence See more O-type stars are hot and luminous. They have characteristic surface temperatures ranging from 30,000 to 52,000 K, emit intense ultraviolet light, and so appear in the visible spectrum as bluish-white.

WebStar classification. The Sun is a as a G2V type star, a yellow dwarf and a main sequence star. Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B stars are uncommon but very bright; M stars are ... WebThe effective temperatures of the O stars lie in the range 30000 K to about 47000 K. For a given subtype, the luminosity class I stars have lower effective temperatures than the main-sequence stars by about 1000 K. The absorption-line spectral types of the supergiants of types O and B reflect electron temperatures which are higher than can be ...
