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:
“Have you not a moist eye, a dry hand, a yellow cheek, a white
beard, a decreasing leg, an increasing belly? Is not your
voice broken, your wind short, your chin double, your wit
single, and every part about you blasted with antiquity? and
will you yet call yourself young?”
—William Shakespeare (1564–1616)
