For HR Diagram Publisher's description


HR Diagram is a Photo & Image software developed by Mario Belloni. After our trial and test, the software is proved to be official, secure and free. Here is the official description for HR Diagram:

This program simulates the Hertzsprung–Russell (HR or H-R) diagram for groups of stars. The diagram is a scatter plot of StellaR Luminosity vs.stellar temperature. The luminosity of stars is proportional to R2 T4., and for Main Sequence stars, their luminosity is also proportional to M3.5. Since the range of stellar luminosities and stellar temperatures is so large, the plot uses a log-log scale.

diagram is a way to understand stellar evolution: stars spend most of
their LiVES on the Main Sequence (the main downward sloping line on the
diagram), while older giant stars are found above this line to the right
and white dwarfs below this line to the left. The HR diagram shows
nearby stars, bright stars, and a user-defined Star. Give HR Diagram a try to fully assess its capabilities!
