White dwarfs are the most numerous members of the stellar graveyard. More than ninety percent of all stars will end their lives as white dwarfs. Research on these objects is fascinating in its own right, requiring developments in atomic data and the study of properties of matter under extreme conditions. However, these studies also have enormous impact on other areas of astrophysics, including: cosmology, the composition of extrasolar planets and fundamental physics. The proceedings of IAU Symposium 357 bring together experts from different branches of science working on white dwarfs, but also astronomers with expertise in a wide range of relevant disciplines. The resulting papers are organized around several key themes: SN Ia progenitors, debris from extrasolar planetary systems, fundamental physics, precision studies of white dwarf structure and stellar physics and Galactic evolution. They provide a framework for guiding the direction of white dwarf research for the next decade.

The emphasis on white dwarf stars and cosmology arises from the most recent advances in cosmological and galactic structure research in which white dwarf stars are playing a very prominent role. Examples are Type Ia supernovae (i.e. white dwarf supernovae), the origin and evolution of the universe, the age of the galactic disk, cosmochronology using white dwarfs in globular clusters and galactic clusters, and the physics of accretion onto compact (very dense) stars. As an assisting guide to the reader, we have included, by invitation, comprehensive review articles in each of the four major areas of the book, white dwarf supernovae, cosmology, accretion physics and galactic structure. The reviews include introductory material that they build upon. The book is suitable and most useful to advanced undergraduates, graduate students and scientific professionals (e.g. astronomers, astrophysicists, cosmologists, physicists).

This book contains the contributed papers and reviews from IAU Colloquium Number 114 on White Dwarfs held at Dartmouth College in August 1988. All the current fields of research in this area are covered including the evolution of white dwarfs, links to progenitors, luminosity functions of white dwarfs, evolution of white dwarfs in binaries, spectroscopy and atmospheric abundances, diffusion, accretion and convective mixing, the mass-radius relation, gravitational redshifts, masses of white dwarfs, and magnetic white dwarfs. Special emphasis has been placed on the intrinsic properties of single white dwarfs. All the articles are by internationally known authorities and contain the most up-to-date information available at the time of writing.

The European Workshop on White Dwarfs was initiated by Prof. V. Weidemann, with the first meeting held in Kiel (FRG) in 1974. Since then a similar workshop has been held almost every two years: Frascati (1976), Tel Aviv (1978), Paris (1981), Kiel (1984), Frascati (1986) and Toulouse (1990). Two major IAU colloquia have also been devoted to the study of white dwarfs (No. 53, Rochester NY, 1979; No. 114, Hanover, NH, 1988). Our most recent meeting, the 8th Workshop, marks a number of important advances in both observational and theoretical studies of white dwarfs. This coincides with a significant expansion in the size of the community active in the field, as was clear from an increase in the number of participants between this workshop (77) and that in Toulouse (46), just two years ago. Key parts of any workshop are the discussion sessions following the pa pers. However, these are difficult to record and, very often, the 'live' flavour of the debates is lost. During this workshop we carried out an experiment, recording the discussion sessions on video tape and then transcribing these later for the proceedings. Although the recordings were made in non-studio conditions with regard to lighting and noise, only a very small part was unin telligible. All participants were given an opportunity to check their questions and answers for scientific accuracy and to correct any errors arising in the transcription process.

The astrophysical process of accretion onto compact central objects is ubiquitous across the universe. The study of white dwarf stars has greatly expanded in recent years, and this book presents, from first principles, the physics of the accretion process onto white dwarfs. Among the resulting phenomena are isolated white dwarfs accreting interstellar gas and dust as they orbit the galactic center, white dwarfs accreting from the debris disks of tidally disrupted asteroids, comets and exoplanets in other exoplanetary systems, white dwarfs accreting from red giant winds in symbiotic variable stars, white dwarfs accreting from Roche lobe-detached main sequence stars, white dwarfs accreting in cataclysmic variables, helium accreting white dwarfs in the ultra-compact AM CVn binaries, accreting white dwarf explosions in classical novae and Type Ia supernovae, the cosmologically critical white dwarf supernovae that led to the discovery of the accelerating expansion of the universe and the existence of dark energy. This book is intended for advanced undergraduates, graduate students, astrophysicists who specialize in white dwarf studies as well as non-specialist scientists.
