Alpha Vulpeculae 19 28 42.2 M0III +24 39 54 Milky Way greater than 1000 Kelvin naked eye star 4.44 for many centuries 1.50 asterism brighter than 5 HR 7405 III

Barnard's star M5 V Ophiuchus greater than 1000 Kelvin 25 years binary star d 1.83 pc 70 percent of all stars 10.25 arcseconds per year Edward Emerson Barnard 100 km/sec main sequence star A faint binary star with the second largest proper motion known. Long-term observations of its light curve suggest a possible third component with a mass about 1.2 that of Jupiter, although this observation has been challenged. 1916 V 2

dMe star dKe star, dMe star greater than 1000 Kelvin d UV Ceti M star hydrogen main sequence star M dwarf with hydrogen emission lines. V

Gamma Sagittae 19 58 45.3 M0III +19 29 32 Milky Way greater than 1000 Kelvin naked eye star 3.47 for many centuries 1.57 asterism brighter than 5 HR 7635 III

Kapteyn's star M0 greater than 1000 Kelvin subdwarf sd 13 light-years +242 km s^-1 CD -45 1841 A nearby high-velocity M0 subdwarf that is both the nearest halo star to the Sun and the nearest star that orbits the Galaxy backward. 1897 VI Jacobus Kapteyn

Kruger 60 AB cooler than G2 greater than 1000 Kelvin P = 44.5 years binary star d 3.93 pc half the stars in the solar neighborhood are members of star systems 12 main sequence star A faint dM binary in the Solar neighborhood. It may be a subluminous star. V 2

Me star greater than 1000 Kelvin M star Star of spectral type M with emission lines in their spectra.

MS star cooler than G2 greater than 1000 Kelvin M star M-type stars with ZrO bands.

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

red giant greater than 1000 Kelvin M star A late-type (K or M) high-luminosity (brighter than M_v = 0) star that occupies the upper right portion of the H-R diagram. Red giants are post-main-sequence stars that have exhausted the nuclear fuel in their cores. The red-giant phase corresponds to the establishment of a deep convective envelope. Red giants in a globular cluster are about 3 times more luminous than RR Lyrae stars in the same cluster. III
