This comprehensive volume reviews our understanding of the origin and evolution of elements, from stellar nucleosynthesis to the chemical evolution of the cosmos. With chapters by leading authorities in the field, it describes models of how the elements are produced by stars, the nuclear processes involved, and how the quantity of elements evolved in our Galaxy and distant galaxies. The observed chemical composition of stars in different locations within our Galaxy and nearby galaxies is discussed, as are the compositions of hot and cold gases, of dust grains found between stars and in meteorites, and of the integrated light from distant galaxies and quasars. This authoritative volume is a valuable resource for graduate students and professional research astronomers.
