On the right, the information panel allows comparisons between the radius, surface temperature, luminosity and mass of the star relative to the Sun. The starting parameters are fora star like the Sun. . A Click the play button below the HertzsprungRussell diagram to show the Sun’s evolution. Once it is complete, you can click on "Data Table” (upper right) to see the final values for each stage in the lifecycle. v CDH#/ 1.
