Subject has spectral type is part of has surface temperature is an instance of has heliocentric radial velocity has distance has discoverer is a kind of has synonym has definition has luminosity class

giant greater than 1000 Kelvin star High-luminosity star that lies above the main sequence on the Hertzsprung-Russell diagram. III

M star cooler than G2 greater than 1000 Kelvin late star Having a spectral type of M, that is, red like Betelgeuse and Antares.

NML Cygnus M6 III Cygnus 700 K giant -43 km s^-1 200 pc Neugebauer, Martz, and Leighton IRC+40448 An infrared star. Its surface temperature is about the same as the surface temperature of Venus. It is a strong OH emitter, and CO has been identified in its spectrum. III
