WebMay 31, 2024 · The tip of the red giant branch is where He is ignited. This takes place "explosively" in a degenerate core if the star is below about 2 M ⊙ (not 5 M ⊙ ), but begins smoothly in higher mass stars. This causes the core to expand, pushes the H-burning shell out and reduces the luminosity.
