📖 Book Summary
Allen's Astrophysical Quantities stands as the definitive reference handbook for astrophysical data, constants, and fundamental parameters that form the backbone of modern astronomy and astrophysics research. Originally conceived by Clabon Walter Allen in the 1950s, this comprehensive reference work has been masterfully updated and expanded by Arthur N. Cox for the 21st century. The book serves as an indispensable compilation of numerical data, physical constants, conversion factors, and empirical relationships that astronomers, astrophysicists, and space scientists rely upon daily in their research and calculations. Rather than following a traditional textbook narrative, this work adopts a systematic, encyclopedic approach organized into clearly defined sections covering stellar properties, planetary data, galactic parameters, cosmological constants, atomic and molecular data, and observational techniques. Each section presents meticulously compiled tables, graphs, and formulas with precise references to their sources and uncertainties. The book's strength lies not in explaining theoretical concepts but in providing the essential quantitative foundation upon which all astrophysical understanding is built. Cox has updated the work to reflect decades of advancement in observational astronomy, incorporating data from space missions, ground-based surveys, and laboratory astrophysics. The presentation maintains scientific rigor while ensuring accessibility through clear organization and comprehensive indexing. This reference work represents the collective knowledge of the astronomical community, distilling complex observational and theoretical results into practical, usable forms. Its relevance extends beyond pure research, serving practitioners in related fields such as planetary science, astrobiology, and space engineering who require reliable astrophysical data for their work.
