This new, fourth, edition of Allen's classic Astrophysical Quantities belongs on every astronomer's bookshelf. It has been thoroughly revised and brought up to date by a team of more than ninety internationally renowned astronomers and astrophysicists. While it follows the basic format of the original, this indispensable reference has grown to more than twice the size of the earlier editions to accommodate the great strides made in astronomy and astrophysics. It includes detailed tables of the most recent data on: - General constants and units - Atoms, molecules, and spectra - Observational astronomy at all wavelengths from radio to gamma-rays, and neutrinos - Planetary astronomy: Earth, planets and satellites, and solar system small bodies - The Sun, normal stars, and stars with special characteristics - Stellar populations - Cataclysmic and symbiotic variables, supernovae - Theoretical stellar evolution - Circumstellar and interstellar material - Star clusters, galaxies, quasars, and active galactic nuclei - Clusters and groups of galaxies - Cosmology. As well as much explanatory material and extensive and up-to-date bibliographies.

Review

"Astrophysical Quantities - APQ to many astrophysicists - has been an essential reference book from its first publication in 1955... Finally the fourth edition has been produced. It has taken 90 contributors to duplicate Allen's heroic single-handed efforts, but the result is well worth the wait. The new book is twice the size of the previous edition and contains many new topics and extended coverage of other topics that have increased in importance in the last three decades. ... the new edition of APQ promises to be as useful as the old one, and most serious astronomers will want a copy..."
