  2. K-type main-sequence star - Wikipedia

    en.wikipedia.org/wiki/K-type_main-sequence_star

    A K-type main-sequence star, also referred to as a K-type dwarf, or orange dwarf, is a main-sequence (hydrogen-burning) star of spectral type K and luminosity class V. These stars are intermediate in size between red M-type main-sequence stars ("red dwarfs") and yellow/white G-type main-sequence stars.

  3. 54 Piscium - Wikipedia

    en.wikipedia.org/wiki/54_Piscium

    54 Piscium is an orange dwarf star approximately 36 light-years away in the constellation of Pisces. In 2003, an extrasolar planet was confirmed to be orbiting the star, and in 2006, a brown dwarf was also discovered orbiting it.

  4. Dwarf star - Wikipedia

    en.wikipedia.org/wiki/Dwarf_star

    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.

  5. Habitability of K-type main-sequence star systems - Wikipedia

    K-type main-sequence stars, also known as orange dwarfs, may be candidates for supporting extraterrestrial life.These stars are known as "Goldilocks stars" as they emit enough radiation in the non-UV ray spectrum [1] to provide a temperature that allows liquid water to exist on the surface of a planet; they also remain stable in the main sequence longer than the Sun by burning their hydrogen ...

  6. Gliese 673 - Wikipedia

    en.wikipedia.org/wiki/Gliese_673

    Gliese 673 is an orange dwarf star in the constellation Ophiuchus. It has a stellar classification of K7V. [2] Main sequence stars with this spectra have a mass in the range of 60–70% of solar mass (M ☉) (comparable to the members of the binary star system 61 Cygni). This star is relatively near the Sun at a distance of about 25 light-years ...

  7. 14 Herculis - Wikipedia

    en.wikipedia.org/wiki/14_Herculis

    14 Herculis is an orange dwarf star of the spectral type K0V. The star has about 98 percent of the mass , 97 percent of the radius , and only 67 percent of the luminosity of the Sun . The star appears to be 2.7 times as enriched with elements heavier than hydrogen (based on its abundance of iron ), in comparison to the Sun. [ 4 ] It may have ...

  8. Main sequence - Wikipedia

    en.wikipedia.org/wiki/Main_sequence

    Main-sequence stars are called dwarf stars, [19] [20] but this terminology is partly historical and can be somewhat confusing. For the cooler stars, dwarfs such as red dwarfs, orange dwarfs, and yellow dwarfs are indeed much smaller and dimmer than other stars of those colors. However, for hotter blue and white stars, the difference in size and ...

  9. 54 Piscium Ab - Wikipedia

    en.wikipedia.org/wiki/54_Piscium_Ab

    54 Piscium b (HD 3651 b), occasionally catalogued as 54 Piscium Ab to differentiate from the brown dwarf in the system, is an extrasolar planet [3] [1] approximately 36 light-years away [4] in the constellation of Pisces. It was discovered orbiting the orange dwarf star 54 Piscium.
