Red giant branch hr diagram
The Hertzsprung–Russell diagram (HR diagram) is a plot of stellar luminosity versus surface temperature for a population of stars. During the core hydrogen burning phase of a Sun-like star's lifetime, it will appear on the HR diagram at a position along a diagonal band called the main sequence. When the hydrogen at the core is exhausted, energy will continue to be generated by hydrogen fusion … WebThe red-giant branch runs from the thin horizontal subgiant branch to the top right, with a number of the more luminous RGB stars marked in red.

WebRed-giant-branch stars have luminosities up to nearly three thousand times that of the Sun ( L☉ ), spectral types of K or M, have surface temperatures of 3,000–4,000 K, and radii up to about 200 times the Sun ( R☉ ). Stars on the horizontal branch are hotter, with only a small range of luminosities around 75 L☉. lampe jean marinThe term red-giant branch came into use during the 1940s and 1950s, although initially just as a general term to refer to the red-giant region of the Hertzsprung–Russell diagram.
