No name was given to the star in Argelander's announcement, but by October of 1856 it was being called R Aquilae, its variable star designation, in the astronomical literature. [ 9 ] [ 10 ] [ 7 ] R Aquilae is an aging red giant on the asymptotic giant branch [ 3 ] with a stellar classification that varies over time, between M5e and M9e, [ 2 ...

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.
