giant branch

[¦jī·ənt ′branch]
(astronomy)
A grouping of stars on the Hertzsprung-Russell diagram that extends upwards and to the right of the main sequence; it represents the first stage of giant-star evolution in which hydrogen fuses to helium in a shell surrounding the core where hydrogen fusion has been exhausted.
