WebThat region is called the instability strip, and is labeled in the schematic HR diagram below. Figure 7.11: HR diagram with instability strip added. The light-colored areas are labeled to show where certain populations of … 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 gap located in the region between A5 and G0 spectral type and between +1 and −…
