Fundamental to our understanding of the universe, stellar astrophysics deals with observations, theoretical understanding, classification, computer simulations and modeling of stars and their evolution. An Introduction to Stellar Astrophysics is a concise textbook containing core content on and detailed examples of stellar physics and stellar astronomy - stellar formation, radiative transfer, stellar atmospheres, stellar interiors, nucleosynthesis, stellar evolution, chemically peculiar stars, and diffusion. A list of problems completes each chapter, and optional content can be tailored to both the lecturer's wishes or the length of the course.
