WebAstronomers use the Hertzsprung-Russell diagram to trace the evolutionary stage of a star. The Hertzsprung diagram where the evolution of sun-like stars is traced. Credits:ESO This is a plot of temperature versus brightness, and as stars are born, live and die, they move in regular patterns around the Hertzsprung-Rusell diagram. Most of the stars occupy the region in the diagram along the line called the main sequence. During the stage of their lives in which stars are found on the main sequence line, they are fusing hydrogen in their cores. The next concentration of stars is on the horizontal branch (helium fusion in the core and hydrogen burning in a shell surrounding the core). Another prominent feature is the Hertzsprung …
