This book on stellar astrophysics is specifically aimed to be used as a textbook for an introductory course on stellar astrophysics. Detailed examples will be given throughout the book to help the student better grasp the concepts. The book will be written in such a way that it could be used for either a one semester or a full year course. There will be core content that is essential for understanding stellar astrophysics, and optional content that can be chosen relative to the lecturers wishes or the length of the course. The core content will not depend on topics covered in the optional sections, thus making this book attractive to lecturers. The book will include chapters on basic concepts, stellar formation, radiative transfer in stars, stellar atmospheres, stellar interiors, nucleosynthesis and stellar evolution and chemically peculiar stars and diffusion.
