A yellow hypergiant is a massive star with an extended atmosphere,a spectral class from late A to early K, an initial mass of as much as 20–50 solar masses, but having lost as much as half that mass. They are amongst the most visually luminous stars, with absolute magnitude (MV) around −9, but also one of the rarest with just a handful known in our galaxy. Yellow hypergiants occupy a region of the Hertzsprung-Russell diagram known as the "Yellow Evolutionary Void", a region where relatively few stars are found and where those stars are generally unstable.

Famous quotes containing the word yellow:
“The prairies were dust. Day after day, summer after summer, the scorching winds blew the dust and the sun was brassy in a yellow sky. Crop after crop failed. Again and again the barren land must be mortgaged for taxes and food and next year’s seed. The agony of hope ended when there was not harvest and no more credit, no money to pay interest and taxes; the banker took the land. Then the bank failed.”
—Rose Wilder Lane (1886–1968)
