  2. Yellow supergiant - Wikipedia

    en.wikipedia.org/wiki/Yellow_supergiant

    Yellow supergiants generally have spectral types of F and G, although sometimes late A or early K stars are included. [1] [2] [3] These spectral types are characterised by hydrogen lines that are very strong in class A, weakening through F and G until they are very weak or absent in class K. Calcium H and K lines are present in late A spectra, but stronger in class F, and strongest in class G ...

  3. V1027 Cygni - Wikipedia

    en.wikipedia.org/wiki/V1027_Cygni

    V1027 Cygni is a luminous yellow supergiant star located in the constellation of Cygnus, about 14,000 light years away. For a time, it was thought that it could be a low-mass post-AGB star, however recent parallax measurements published in Gaia DR3 have shown this to likely not be the case, and instead it is likely a massive yellow supergiant star.

  4. List of nearest supergiants - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_supergiants

    This is a list of the nearest supergiant stars to Earth, located at a distance of up to 1,100 light-years (340 parsecs) from Earth. Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list.

  5. Giant star - Wikipedia

    en.wikipedia.org/wiki/Giant_star

    Type I Cepheid variables, more luminous still and mostly supergiants, with even longer periods; Delta Scuti variables, includes subgiant and main-sequence stars. Yellow giants may be moderate-mass stars evolving for the first time towards the red-giant branch, or they may be more evolved stars on the horizontal branch.

    en.wikipedia.org/wiki/Delta_Canis_Majoris

    Artist's illustration of Wezen, a yellow supergiant 1,600 light-years away in the Canis Major constellation. Delta Canis Majoris is a supergiant of class F8. It is 14 to 15 times more massive than the Sun, [8] but around 190 times larger. It lies at a distance of 1,600 light-years from Earth and has a luminosity 35,000 times the Sun's ...

  7. Yellow hypergiant - Wikipedia

    en.wikipedia.org/wiki/Yellow_hypergiant

    Intrinsic variable types in the Hertzsprung–Russell diagram showing the Yellow Hypergiants above (i.e. more luminous than) the Cepheid instability strip. A yellow hypergiant (YHG) is a massive star with an extended atmosphere, a spectral class from A to K, and, starting with an initial mass of about 20–60 solar masses, has lost as much as half that mass.

    Doritos are a revered snack for many. Now, scientists have found one of the ingredients in the triangle-shaped tasty tortilla chips has a superpower – it can make the skin of mice transparent.

  9. V810 Centauri - Wikipedia

    en.wikipedia.org/wiki/V810_Centauri

    V810 Centauri is a double star consisting of a yellow hypergiant [3] primary (V810 Cen A) and blue giant secondary (V810 Cen B). It is a small amplitude variable star , entirely due to the supergiant primary which is visually over three magnitudes (about 12x) brighter than the secondary. [ 6 ]
