  2. Regulus - Wikipedia

    en.wikipedia.org/wiki/Regulus

    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.

  3. Dwarf star - Wikipedia

    en.wikipedia.org/wiki/Dwarf_star

    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 ...

    en.wikipedia.org/wiki/LHS_2065

    LHS 2065 is a red dwarf star, one of the smallest stars ever found with around 8.2% the mass of the Sun and a diameter only 10% greater than Jupiter. [6] It is one of the few ultracool dwarfs known to have flare activity, emmiting one flare every 33 hours, [5] and is also an active X-ray emitter.

    GD 165 B is an L-Type brown dwarf with a temperature of about 1,750 K, a mass of about 63 M J, and a radius of 1.00 R J. [8] GD 165B is separated by 123±12 astronomical units from its host white dwarf. It is the second closest spacially resolved brown dwarf after PHL 5038, which has a separation of around 69 AU. [14]

  7. YZ Ceti - Wikipedia

    en.wikipedia.org/wiki/YZ_Ceti

    YZ Ceti is a red dwarf star in the constellation Cetus. Although it is relatively close to the Sun at just 12 light years, this star cannot be seen with the naked eye. It is classified as a flare star that undergoes intermittent fluctuations in luminosity. YZ Ceti is about 13 percent the mass of the Sun and 17% of its radius.

  9. RR Caeli - Wikipedia

    en.wikipedia.org/wiki/RR_Caeli

    RR Caeli was first noted to be a high-proper motion star in 1955 by Jacob Luyten, and given the designation LFT 349.. This star system consists of a red dwarf of spectral type M6 and a white dwarf that orbit each other every seven hours; the former is 18% as massive as the Sun, while the latter has 44% of the Sun's mass.
