Variable stars are those that change brightness. They come in many varieties, but each one provides important information about the star: its properties, its internal structure, and its evolution. 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. Intended for anyone with some background knowledge of astronomy, it is especially suitable for undergraduate students and experienced amateur astronomers.

Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.
Observing Variable Stars: A Guide for the Beginner

Variable star astronomy is one field which still allows amateur astronomers to make significant contributions to the advancement of science. Everyone can play a part in variable star observations, using a small telescope, binoculars, or even the naked eye. Written by an award-winning astronomer, Observing Variable Stars provides a comprehensive introduction to the field of variable star observation for the amateur. The book begins with advice on binoculars and telescopes, and on how and when to observe stars effectively. Levy then explains the ways in which to interpret variation in light output in terms of the life of a star, from birth to sometimes violent death. All the major variables are described and classified, as well as other variable objects such as active galaxies, asteroids, comets, and the sun. The book also illustrates how astrophysicists interpret variations in light output in terms of the evolution of stars. Observing Variable Stars contains a seasonal guide to the night sky usable in all latitudes. Throughout, practical observations serve to complement the text, making this an enjoyable, readable introduction to an exciting area of astronomy.
The AAVSO Manual for Visual Observing of Variable Stars is a comprehensive guide to variable star observing. It incorporates a lot of the basic information in the Manual for Observing Variable Stars, published in 1970, as well as information from various AAVSO observing materials published since then. The most recent revision occurred in January, 2005. This manual provides up-to-date information for making variable star observations and reporting them to the AAVSO.
