HR 5171, also known as V766 Centauri, is a yellow hypergiant in the constellation Centaurus. It is said to be either an extreme red supergiant (RSG) or recent post-red supergiant (Post-RSG) yellow hypergiant (YHG), both of which suggest it is one of the largest known stars. The star's diameter is uncertain but likely to be between 1,100 and ...
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.
Notable examples of hypergiants include the Pistol Star, a blue hypergiant located close to the Galactic Center and one of the most luminous stars known; Rho Cassiopeiae, a yellow hypergiant that is one of the brightest to the naked eye; and Mu Cephei (Herschel's "Garnet Star"), one of the largest and brightest stars known.
A yellow hypergiant star, similar to V382 Carinae, that is also visble to the naked eye. CW Leonis: 560 [74] L/T eff: The nearest carbon star. V509 Cassiopeiae: 511 ± 112 [35] AD A variable yellow hypergiant whose size varied from around 680 R ☉ in 1950–1970 to 910 R ☉ in 1977, and later decreased to 390 R ☉ in the 1990s. [75] V382 ...

Other similarities to the yellow hypergiant mentioned above include the similar absorption line spectra. The star's temperature was estimaged to be 8,000 K and the spectral type A8-F0Ia was assigned to this star. [8] A 2016 paper got a similar luminosity for the star (873,000 L ☉) and a slightly lower temperature of 6,970 K. [9]

V382 Carinae, also known as x Carinae (x Car), is a yellow hypergiant in the constellation Carina. It is a G-type star with a mean apparent magnitude of +3.93, and a variable star of low amplitude.
