Compiled by a team of experts, this textbook introduces the properties and evolution of the most immediately visible objects in the Universe - stars. Designed for elementary university courses in astronomy and astrophysics, it starts with a detailed discussion of our nearest star, the Sun, and describes how solar physicists have come to understand its internal workings. It then considers how we study the basic physical properties and life-cycles of more distant stars, culminating with a discussion of more 'exotic' objects, such as neutron stars and black holes. This second edition has a greater emphasis on the physical and spectral properties of stars, introducing stellar atmospheres, spectral line formation and the role of binary stars in the formation of compact objects. Avoiding complex mathematics, and generously illustrated in colour throughout, this accessible text is ideal for self-study and will appeal to both amateur astronomers and undergraduate students.

This well-received textbook has been designed by a team of experts for introductory courses in astronomy and astrophysics. Starting with a detailed discussion of our Galaxy, the Milky Way, it goes on to give a general introduction to normal and active galaxies including models for their formation and evolution. The second part of the book provides an overview of cosmological models, discussing the Big Bang, dark energy and the expansion of the Universe. This second edition has been updated to reflect the latest developments and observations, while still probing the unresolved questions at the forefront of research. It contains numerous learning features such as boxed summaries, exercises with full solutions, a glossary and a supporting website hosting further teaching materials. Written in an accessible style that avoids complex mathematics, and illustrated in colour throughout, this text is suitable for self-study and will appeal to amateur astronomers as well as students.
