This book is a comprehensive survey of the current research in the field of cataclysmic variables and low-mass X-ray binaries. These compact binaries contain a Roche-lobe filling low-mass star and an accreting white dwarf, neutron star, or black hole. In the turbulent process of accretion, a broad and highly variable spectrum of radiation is produced. The interpretation of the behaviour of these binaries is the present work of hundreds of astronomers, many of whom contributed to this volume. Among the topics covered here are observations and theories of low-mass neutron star and black hole binaries, magnetic and non-magnetic white dwarf binaries, transient X-ray sources, novae, and binary pulsars, as well as theories of the evolution of these binaries. The book is based on material presented at the 11th North American Workshop on Cataclysmic Variables and Low Mass X-ray Binaries held in Santa Fe, New Mexico, in October 1989. Each contribution contains sufficient in-depth information to be of use to the specialist, while the breadth of subjects covered will ensure a wide audience among advanced undergraduates and graduate students.
