First directly observed granulation patterns on a star's surface outside the Solar System. Antares α Sco A 41.3 ± 0.1: 680 [19] 553 [20] Very Large Telescope – VLTI/AMBER [21] [22] 2017 [citation needed] Betelgeuse α Ori 50: 640 [23] –764 [24] 643 ± 146: Hubble – GHRS [1] 1995: First star with a resolved image outside the Solar System ...
An asterism is an observed pattern or group of stars in the sky. Asterisms can be any identified pattern or group of stars, and therefore are a more general concept than the 88 formally defined constellations. Constellations are based on asterisms, but unlike asterisms, constellations outline and today completely divide the sky and all its ...
The Bright Star Catalogue, which is a star catalogue listing all stars of apparent magnitude 6.5 or brighter, or roughly every star visible to the naked eye from Earth, contains 9,096 stars. [1] The most voluminous modern catalogues list on the order of a billion stars, out of an estimated total of 200 to 400 billion in the Milky Way .
Asymptotic giant branch – Stars powered by fusion of hydrogen and helium in shell with an inactive core of carbon and oxygen; Galaxy color–magnitude diagram – Chart depicting the relationship between brightness and mass of large star systems; Hayashi track – Luminosity–temperature relationship in 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
Theoretical limit of star size (Large Magellanic Cloud) ≳1,550 [9] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of stars. Assumes an effective temperature of 3,545 K. Reported for reference: HV 888 1,477 [105] –1,584 [106] Large Magellanic Cloud L/T eff: HD 269551 A 1,439 [107 ...
A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. [1] They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. [2]
