- Q863936 abstract "A K-type main-sequence star (K V), also referred to as an orange dwarf orK 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 and yellow G-type main-sequence stars. They have masses between 0.45 to 0.8 times the mass of the Sun and surface temperatures between 3,900 and 5,200 K., Tables VII, VIII.Better-known examples include Alpha Centauri B (K1 V) and Epsilon Indi. These stars are of particular interest in the search for extraterrestrial life because they are stable on the main sequence for a very long time (15 to 30 billion years, compared to 10 billion for the Sun). This may create an opportunity for life to evolve on terrestrial planets orbiting such stars. K-type stars also emit less ultraviolet radiation (which can damage DNA and thus hamper the emergence of life) than G-type stars like the Sun. K-type main-sequence stars are about three to four times as abundant as G-type main-sequence stars, making planet searches easier.".
