stellar evolution models

Stellar evolution models describe the life cycle of stars, illustrating how they form, change, and eventually die. Stars begin as clouds of gas and dust that collapse under gravity. As they fuse hydrogen into helium, they shine and evolve through different stages, such as becoming a red giant. Eventually, they can shed outer layers or explode in a supernova, leaving behind remnants like neutron stars or black holes. These models help scientists understand the processes that govern stars and contribute to the formation of elements in the universe, impacting everything from galaxy formation to life on Earth.
