WebThe original H-R diagram was published by Russell in 1913. Giant branch The giant branch is a conspicuous sequence of red stars with large radii in the Hertzsprung-Russell diagram of a typical globular cluster, which extends upward from the main-sequence turnoff point to the red giant tip. Hayashi track Main entry. Henyey track WebOn the H–R diagram, the star therefore leaves the main-sequence band and moves upward (brighter) and to the right (cooler surface temperature). Over time, massive stars become red supergiants, and lower-mass stars like the Sun become red giants.
