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. WebAs most stars of this type are cooler and redder, the term red giant is often used. A similar comparison with an even brighter G star at M = –7.5 produces a size that is 310 times that of the Sun, or a radius of 220 million km, placing the photosphere at the orbit of Mars if this star were to replace the Sun in the solar system. sec college football standings https://integrative-living.com
