Hertzsprung–Russell (H-R) Diagrams
written by
Mario Belloni
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 stellar temperatures is so large, the plot uses a log-log scale. The diagram is a way to understand stellar evolution.
The HR diagram shows nearby stars, bright stars, and a user-defined star. One can also show the blackbody radiation curve and the user-defined star. The radius of the user-defined star (in Rsun) and the temperature of the user-defined star in Kelvin (5780 K is Tsun) can be changed. Please note that this resource requires at least version 1.5 of Java (JRE). Please note that this resource requires Java3D.
