Evolved stars
Evolved stars are stars that have aged and undergone significant changes after using up most of their fuel. They expand and cool, becoming larger and often brighter, forming different types such as red giants or supergiants. This stage occurs after the star has exhausted hydrogen in its core and begins fusing heavier elements or undergoing structural changes. These stars are crucial for enriching the universe with elements, as they shed material into space, contributing to the formation of new stars and planets. Their evolution provides insight into the life cycle of stars and the dynamic nature of our cosmos.
