In recent years knowledge of nova phenomena has grown significantly due to the advent of new observational facilities, both on the ground and in space, and considerable advances in theoretical work. This second edition has been fully updated and revised and contains new contributions covering important developments in this field, and reflecting on interesting new insights into classical novae. The book examines thermonuclear processes, the evolution of nova systems, nova atmospheres and winds, the evolution of dust and molecules in novae, nova remnants, and observations of novae in other galaxies. It includes observations across the electromagnetic spectrum, from radio to gamma rays, and discusses some of the most important outstanding problems in classical nova research. This is the only book devoted solely to the study of classical novae, and as such is an important reference for researchers actively engaged in the subject and graduate students seeking an introduction.
