Définition(s)
- An M star is a cool, red star, of spectral type M, with a surface temperature of less than 3,600°C. Molecular absorption bands are prominent in the spectrum, with bands of titanium oxide becoming dominant at the lower end of the temperature range. Main sequence M stars, known as red dwarfs, have a mass of less than 0.5 the mass of the Sun and a luminosity of less than 0.08 the luminosity of the Sun; examples include the nearby Proxima Centauri and Barnard's Star.
