Browsing: Stellar Evolution
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, its life cycle can span from a few million years for the most massive stars to trillions of years for the least massive ones. The journey begins with the gravitational collapse of a cloud of gas and dust, leading to the formation of a protostar when the core temperature gets high enough to start nuclear fusion. In this phase, hydrogen nuclei fuse to form helium, releasing energy that makes the star shine.
