The Hertzsprung–Russell diagram showing the location of main sequence dwarf stars and white dwarfs. A dwarf star is a star of relatively small size and low luminosity. Most main sequence stars are dwarf stars. The meaning of the word "dwarf" was later extended to some star-sized objects that are not stars, and compact stellar remnants that ...
The red dwarf stars are considered the smallest stars known, and representative of the smallest star possible. [64] [65] [66] Brown dwarf: WISEA 1810−1010: 0.067 0.655 7.29 46,840 km (29,110 mi) Brown dwarfs are not massive enough to build up the pressure in the central regions to allow nuclear fusion of hydrogen into helium.

R Centauri is a Mira variable star with a minimum magnitude of 11.8 and a maximum magnitude of 5.3; it is about 1,250 light-years from Earth and has a period of 18 months. [2] V810 Centauri is a semiregular variable. BPM 37093 is a white dwarf star whose carbon atoms are thought to have formed a
Regulus A is a binary star consisting of a blue-white subgiant star of spectral type B8, which is orbited by a star of at least 0.3 solar masses, which is probably a white dwarf. The two stars take approximately 40 days to complete an orbit around their common centre of mass.
TRAPPIST-1 is a cool red dwarf star [c] with seven known exoplanets. It lies in the constellation Aquarius about 40.66 light-years away from Earth, and has a surface temperature of about 2,566 K (2,290 °C; 4,160 °F). Its radius is slightly larger than Jupiter and it has a mass of about 9% of the Sun.
