A lucid introductory textbook for undergraduate students in physics, astronomy, planetary science and applied mathematics taking a course on the physics of stars.This lucid textbook provides undergraduate students with a clear and comprehensive introduction to the theory that predicts the birth, life and death of stars and their internal structure. It requires only basic introductory undergraduate physics and mathematics, and no prior knowledge of astronomy. Throughout this book, emphasis is placed on the basic physical principles. Processes are explained in the simplest terms but without compromising mathematical rigor, and exercises with solutions are included to help the reader. This textbook provides a stimulating introduction for undergraduates in astronomy, physics, planetary science and applied mathematics taking a course on the physics of stars.This lucid textbook provides undergraduate students with a clear and comprehensive introduction to the theory that predicts the birth, life and death of stars and their internal structure.

This textbook provides a stimulating introduction for undergraduates in astronomy, physics, planetary science and applied mathematics taking a course on the physics of stars.Using fundamental physics, the theory of stellar structure and evolution is able to predict how stars are born, how their complex internal structure changes, what nuclear fuel they burn, and their ultimate fate. This undergraduate textbook provides a clear, methodical introduction to the theory of stellar structure and evolution. Starting from general principles and axioms, step-by-step coverage leads students to a global, comp
