nuclear astrophysics

Nuclear astrophysics is a branch of astronomy that applies physics and chemistry to understand celestial objects and the processes that govern their formation and evolution. It specifically studies the nuclear reactions that power stars, like our Sun.123

Stars generate energy through nuclear fusion, primarily by converting hydrogen into helium. This process is fundamental to nucleosynthesis, the creation of heavier elements within stars. The energy released during fusion is a result of the binding energy within atomic nuclei. Stellar evolution is driven by these ongoing fusion reactions and the resulting changes in the star's composition and stability. When a star exhausts its fuel, its core collapses, leading to the formation of white dwarfs, neutron stars, or black holes, depending on the star's mass.314
