View source for K-type main-sequence star

A '''K-type main sequence star''', also referred to as a '''K-type dwarf''' or an '''orange dwarf''', is a [[Main sequence star|main sequence]] ([[hydrogen]]-burning) star of [[spectral type]] K and [[luminosity class]] V. These stars are intermediate in size between red [[:Category:Main Sequence M-type|M-type main sequence stars]] ("red dwarfs") and yellow/white [[:Category:Main Sequence G-type|G-type main-sequence stars]]. They have masses between 0.6 and 0.9 times the mass of [[Sol]] and surface temperatures between 3,900 and 5,300 K. These stars are of particular interest in the search for extraterrestrial life due to their stability and long lifespan. Well-known examples include Alpha Centauri B (K1 V) and Epsilon Indi (K5 V).
