This classic text, aimed at senior undergraduate and beginning graduate students in physics and astronomy, presents a wide range of astrophysical concepts in sufficient depht to give the reader a quantitative understanding of the subject. Emphasizing physical concepts, the book out lines cosmic events but does not portray them in detail : it provides a series of astrophysical sketches. For this third edition, nearly every part of the text has been reconsidered and rewritten ; new sections have been added to cover recent developments, and most of the rest have been revised and brought up to date. The book begins with an outline of the scope of modern astrophysics and the elementary problems concerning the scale of cosmic objects and events. The basic physics needed to answer these questions is developed in the next chapters, using specific astronomical processes as examples. The second half of the book enlarges on the topics introduced at the beginning and shows how we can obtain quantitative insights into the structure and evolution of stars, the dynamics of cosmic gases, the large-scale behavior of the universe, and the origins of life. The emphasis is on astrophysics, so astronomical objects (white dwarfs, supernovae, comets, quasars) are mentioned throughout the text whenever the relevant physics is discussed rather than in individual sections. To compensate, there is an appendix that gives a brief background of astronomical concepts for students unfamiliar with astronomical terminology, as well as a comprehensive index. The extensive bibliography refers to other sources that treat individual topics in detail.Diagram. One of the most useful diagrams in all astronomy is the Hertzsprung- Russell, H-R diagram. It presents a comparison of brightness and temperature plotted for any chosen class of stars. Chapter 2 shows that the diagram is valuable inanbsp;...
