WebbMost stars are grouped into a small number of spectral types. The Henry Draper Catalogue and the Bright Star Catalogue list spectral types from the hottest to the coolest stars ( see stellar classification ). These types are designated, in order of decreasing temperature, by the letters O, B, A, F, G, K, and M. WebbStars are also grouped into spectral types or classes by color. In general, a star's temperature determines its color, from red to blue-white. Spectral types are named with a letter. The seven main types are M, K, G, F, A, B and O. M stars are the coldest stars and O stars are the hottest.

WebbNotes about certain spectral classes: *In general a hot star’s spectrum looks smoother than a cooler star’s spectrum. *In very hot stars (> 10,000 K) most of the Hydrogen gas in the star’s atmosphere will be ionized. Since an ionized Hydrogen atom has no electron it cannot produce any spectral lines, thus the Hydrogen lines are weak in O ...

WebbThe coolest stars are red and are called M-type. In order of increasing temperature, the spectral classes are M (red), K (orange), G (yellow), F (yellow-white), A (white), B (blue-white), O (blue).

Webb10 nov. 2024 · MK (Morgan et al. 1973) is a widely used method in spectral classification, which is based on spectral features of a small-scale standard star. The MK system is based on the temperature of the star from high to low, which divides the stellar spectrum into seven categories.
