Geneva Stellar Evolution Code

The Geneva Stellar Evolution Code is a sophisticated computer program used by astronomers to simulate how stars develop and change over time. It models key processes like nuclear fusion, energy transport, and the effects of rotation and mass loss within stars. By inputting different initial star properties, scientists can predict a star's lifecycle stages, including its size, brightness, and lifespan. This code helps researchers understand star behavior, compare with observations, and improve knowledge about stellar physics without making overly simplified assumptions.
