Stellar Physics is the branch of astrophysics that focuses on the study of stars, their formation, evolution, and eventual demise. It encompasses various processes, including nuclear fusion, which powers stars like our Sun, and the intricate life cycles that lead to phenomena such as supernovae and black holes. Understanding Stellar Physics helps scientists unravel the mysteries of the universe, including the distribution of elements and the dynamics of galaxies. By studying different types of stars, from red dwarfs to giants, researchers gain insights into the fundamental processes that govern the cosmos and the origins of the elements that make up everything around us.
