K-type main-sequence star - Wikipedia

WebA K-type main-sequence star, also referred to as a K-type dwarf or an orange dwarf, is a main-sequence ( hydrogen -burning) star of spectral type K and luminosity class V. These stars are intermediate in size between red M-type main-sequence stars ("red dwarfs") and yellow/white G-type main-sequence stars. The term was originally coined in 1906 when the Danish astronomer Ejnar Hertzsprung noticed that the reddest stars – classified as K and M in the Harvard scheme – could be divided into two distinct groups. They are either much brighter than the Sun, or much fainter. To distinguish these groups, he called them "giant" and "dwarf" stars, the dwarf stars being fainter and the giants being brighter than the Sun. shxw\u0027ōwhámél first nationWebMar 18, 2024 · Stars with luminosity classifications of III and II (bright giant and giant) are referred to as blue giant stars.
