Hertzsprung�Russell (H-R) Diagrams

The Hertzsprung�Russell (H-R) Diagrams model simulates Hertzsprung�Russell (HR or H-R) diagram for groups of stars. The diagram is a scatter plot of steller luminosity vs. stellar temperature. The luminosity of stars is proportional to the star's radius squared and its temperature to the fourth power, and for Main Sequence stars, their luminosity is also proportional to their mass to the 3.5 power. Since the range of stellar luminosities and...
