dwarf greater than 1000 Kelvin d star main sequence star Star with mass equal to or less than that of the sun. More generally, any star on or below the main sequence in the Hertzprung-Russell diagram. V

K star cooler than G2 3600 to 5000 K orange to red late star Cool star with spectral type K with spectra resembling those of sunspots, in which the hydrogen lines have been greatly weakened. The HK lines (q.v.) reach their greatest intensity. Strongest lines are Ca I (4227 Å) and the G-band (4303 Å).

Epsilon Eri K2 V Eridanus 3600 to 5000 K dwarf orange to red d 3.30 pc 4 main sequence star In 1973 van de Kamp announced that this star has a planet-like object in orbit around it at a distance of about 8 AU and with a period of about 25 years. V
