Major Branches on the H-R Diagram: The H-R diagram is an important astronomical tool for understanding how stars evolve over time. Stellar evolution can not be studied by observing individual stars as most changes occur over millions and billions of years. Astrophysicists observe numerous stars at various stages in ...
WebJul 15, 2024 · The Hertzsprung-Russell diagram. The simple answer to this kind of question in science was the same then as it is now: make a plot and see what happens.
