WebJan 12, 2024 · When we then plot luminosity (or absolute brightness) versus color (or temperature), the stars all fall along a narrow strip in the diagram. This is the H-R Diagram. So the right way to think about an H-R Diagram. It is telling us that a star’s color (or temperature) and its luminosity are related. Blue stars are more luminous than red stars.

WebRed giants were identified early in the 20th century when the use of the Hertzsprung–Russell diagram made it clear that there were two distinct types of cool stars with very different sizes: dwarfs, now formally known as … 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. psychologist panama city beach
