Introductory astronomy & astrophysics Upplaga 4

This focused, advanced undergraduate text provides broad coverage of astronomy and astrophysics with a strong emphasis on physics. Many researchers, faculty, and graduate students use this book as a reference. This text has an algebra and trigonometry prerequisite, but calculus is preferred. Features: * "Concept Applications" are fully worked-out, in-chapter problems that focus on an important concept found within that chapter. * "Key Equations and Concepts" neatly summarize the important equations and concepts found in each chapter. New to this edition: * Many new problems have been added, most 3rd Edition problems remain. * Physics Prelude serves as preview and preorganizer of the physics at a level appropriate to the book and the course. * Reorganization of Part 3--Chapters on stellar evolution are now consecutive. * Key new astronomical material further enhances the text. * "Hale-Bopp Comet Update" has been added after Chapter 26.
