Horizontal branch. The horizontal branch (HB) is a stage of stellar evolution that immediately follows the red giant branch in stars whose masses are similar to the Sun's. Horizontalbranch stars are powered by helium fusion in the core (via the triplealpha process) and by hydrogen fusion (via the CNO cycle) in a shell surrounding the core.
