The Jovian planet was the first discovered around a red dwarf. [2] [3] First discovered with giant planet(s) Gliese 876: 1998 Gliese 876 b: The giant planet was the first planet discovered around a red dwarf. [2] [3] First discovered with terrestrial planet(s) Kepler-42 : 2012 KOI-961 b KOI-961 c KOI-961 d
This was once the smallest known actively fusing star, when found in 2005, through 2013. It is the smallest eclipsing red dwarf, and smallest observationally measured diameter. [102] [103] [104] CoRoT-15b: 82,200 Brown dwarf [105] VB 10: 82,300 Red dwarf: It was the smallest known star from 1948 to 1981. [106] TRAPPIST-1: 82,925
Of those, 103 are main sequence stars: 80 red dwarfs and 23 "typical" stars having greater mass. Additionally, astronomers have found 6 white dwarfs (stars that have exhausted all fusible hydrogen), 21 brown dwarfs, as well as 1 sub-brown dwarf, WISE 0855−0714 (possibly a rogue planet ).
Dwarf star with no other qualification generally refers to a main-sequence star, a star of luminosity class V: main-sequence stars (dwarfs). Example: Achernar (B6Vep) [2] Red dwarfs are low-mass main-sequence stars. Yellow dwarfs are main-sequence (dwarf) stars with masses comparable to that of the Sun. Orange dwarfs are K-type main-sequence stars.
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source
M-type main-sequence stars are main-sequence stars (luminosity class V) of spectral type M. ... List of red dwarfs; Ultra-cool dwarf; 0–9. 2MASS J01225093−2439505;
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.
Main-sequence stars, also called dwarf stars, are stars that fuse hydrogen in their cores. These are dwarfs in that they are smaller than giant stars, but are not necessarily less luminous. For example, a blue O-type dwarf star is brighter than most red giants. Main-sequence stars belong to luminosity class V.
