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 … WebApr 8, 2024 · During this phase, the path the star will follow in the HR diagram is almost horizontal to the right of its position on the Main Sequence. Stars in this phase are usually referred to as subgiants. But I still can't understand. ... The reason the luminosity eventually rises steeply on the red giant branch is that as the degenerate core starts to ...

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☉ ).
