The planet is destroyed when the red supergiant Rao becomes a supernova. Many post-AGB stars receive spectral types with supergiant luminosity classes. Betelgeuse is a red supergiant that has evolved from an O-type main sequence star. Two spectroscopic companions have been proposed to the red supergiant star. There is an upper limit to the luminosity of a red supergiant at around . KY Cygni is a large luminous cool supergiant with a strong stellar wind. A bright cool giant star can easily be larger than a hotter supergiant. It is a blue-white supergiant of spectral type B2Iab, around 404 light-years from Earth. The classical example is Antares B, the blue companion of the red supergiant Antares. A D type supergiant is called a cD galaxy. Stars more massive than about cannot expand into a red supergiant. The primary is a yellow supergiant that is itself intrinsically variable. Pyre is a 2017 action role-playing video game developed and published by Supergiant Games. The two teams were the Rising Pune Supergiant and the Gujarat Lions. They won matches against KXIP and Rising Pune Supergiant, the new entrant in the tournament.
