You don't appear to have Javascript enabled so you won't be able to use the interactive features of Star In A Box. However, you can still download data to make your own investigations of how the brightness, size and mass of stars change as they go through their lives: 0.2 solar mass star; 0.65 solar mass star; 1 solar mass star; 2 solar mass star

Welcome to the Digital Demo Room, Stellar Structure and Evolution Simulator! The purpose of this simulator is for the user to be able to create and view simulations which evolve stars on a Hertzsprung-Russell (HR) diagram.
As part of its educational mission, the Space Science Institute has developed Starchitect, a free astronomy education game that explores stellar and planetary evolution. Build stars and planets, then watch as they evolve in scaled real time (a million years to the minute).
Starlab is a collection of modular software tools designed to simulate the evolution of stars and stellar systems, and analyze the resulting data.
This site provides documentation for Modules for Experiments in Stellar Astrophysics (MESA), an open-source 1D stellar evolution code.
Stellar evolution calculations (i.e., stellar evolution tracks and detailed information about the evolution of internal and global properties) are a basic tool that enable a broad range of research in astrophysics.
Stellar physics and evolution calculations enable a broad range of research in astrophysics. Modules for Experiments in Stellar Astrophysics (MESA) is a suite of open source, robust, e cient, thread-safe libraries for a wide range of ap-plications in computational stellar astrophysics. A 1-D stellar evolution module,
