Conceptual Astrophysics is intended for introductory (non-calculus based) astronomy. It applies our understanding of physics to astronomy and highlights recent developments in the discipline. Readers are provided with a comprehensive exploration of key theories, ideas, and processes, and develop a strong base of knowledge to support further study.


The text is intended to cover a two-semester sequence. The first semester includes three parts. Part 1 introduces the origins of solar system astronomy and measurements of space and time. Part II discusses the physics of motion, gravity and light. Part III is an in-depth look at the origin, organization, geology, atmospheres, and magnetic fields of the solar system, culminating with the Sun.



The second semester includes two parts. Part IV introduces the origins of stellar astronomy, with another look at light, and depicts stellar life cycles from formation through destruction. Part V expands our view to the Milky Way, galaxies, cosmology, and discusses the possibility of extraterrestrial life.



Each chapter incorporates key terms, important individuals, conceptual questions, and suggested activities. Conceptual Astrophysics is an ideal text for courses in introductory astronomy.
