Lectures on Astrophysics provides an account of classic and contemporary aspects of astrophysics, with an emphasis on analytic calculations and physical understanding. It introduces fundamental topics in astrophysics, including the properties of single and binary stars, the phenomena associated with interstellar matter, and the structure of galaxies. Nobel Laureate Steven Weinberg combines exceptional physical insight with his gift for clear exposition to cover exciting recent developments and new results. Emphasizing theoretical results, and explaining their derivation and application, this book provides an invaluable resource for physics and astronomy students and researchers.

‘This book is entitled ‘Lectures on Astrophysics’ and indeed is based on notes for courses on astrophysics delivered in recent years. Thus the material is road-tested and, as is necessary in any lecture course, compromises have been made on the scope of the work in order to make the treatment digestible.’

‘I would have to say that the stronger you are at mathematics, the more you will get out of the book. But even if you feel that you are not heavily mathematically inclined, the explanatory texts in the equation-free paragraphs are a model of clarity. The book is strong on modern topics, so, if you haven’t updated your astrophysics teaching notes for a long time, and you wish to update them with modern topics, this is just the very book you need.’

‘Steven Weinberg has written a self-contained and relatively short account of the foundations of astrophysics, from stars to galaxies. The result is extremely pleasant and particularly suitable for students and young practitioners in the field … Weinberg’s books always stimulate a wealth of considerations on the mutual interplay of particle physics, astrophysics and cosmology, and the problems of dark matter, dark energy, gravitational waves and neutrino masses are today so interlocked that it is quite difficult to say where particle physics stops and astrophysics takes over. If we want to understand the developments of fundamental physics in coming years, Lectures on Astrophysics will be an inspiring source of reflections and a valid reference.’

‘… based on lectures delivered in 2016 and 2017. In a text that is clear and concise, and supported by analytical equations that do not require a computer to solve, Weinberg frequently offers the reader insight into the essential physical concepts by doing approximate calculations. He also provides twelve problems for the reader to attempt to solve, … The book is strongly recommended to libraries supporting readers at the graduate and advanced undergraduate level.’
