This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.

Industry Reviews

'If you want a comprehensive guide to the science of variable stars, you can't go wrong with a book written by John Percy, a world authority on variable star observation.' BBC Sky at Night Magazine 'tightly written, and frequently interspersed with figures and graphs, the book contains an enormity of fact and discussion ... a foremost authority on Variable Stars, and is a marvellous repository of information. As such it is an ideal textbook for a serious student, or a reference book for the amateur astronomer.' Astronomy & Space '... the book achieves its aim of providing an overview of variable-star astronomy, and given the size of the field this is no mean feat. It comes with an excellent index ...' The Observatory 'It seems likely to me that Understanding Variable Stars was written with the American Association of Variable Star Observers members in mind. ...It is certainly the most up-to-date readable description of the various types of starts and what is known about each. ...Basically, if you observe variable starts, you should read and probably own this book. Thank you Dr. Percy!' American Association of Variable Star Observers Bookstore
