Cosmochemistry

Thirty Years of Astronomical Discovery With UKIRT, 2010
Cosmochemistry is a rapidly evolving field of planetary science and the second edition of this classic text reflects the exciting discoveries made over the past decade from new spacecraft missions. Topics covered include the synthesis of elements in stars, behaviour of elements and isotopes in the early solar nebula and planetary bodies, and ...

Cosmochemistry

, 2004
The chemical composition of the Universe has evolved over billions of years. A host of astrophysical processes and observations must be understood in order to explain why celestial objects have the chemical compositions observed. Originally published in 2004, this book contains the lectures delivered at the XIII Canary Islands Winter School of ...

An introduction to cosmochemistry

Geochimica et Cosmochimica Acta, 1995
This textbook describes the composition and evolution of material objects in the universe. The survey begins with a discussion of terrestrial materials and ends with the composition of quasars and distant galaxies. There are two main themes: chemical processes responsible for the abundances we observe, and nuclear processes in which the chemical ...

Extrasolar Cosmochemistry

Annual Review of Earth and Planetary Sciences, 2014
Evidence is now compelling that elements heavier than helium in many white dwarf atmospheres have accumulated by accretion from orbiting rocky bodies, often larger than 100 km in diameter, such as asteroids. Consequently, we now possess a powerful tool to measure the elemental constituents of extrasolar minor planets.

Cosmochemistry of Lithium

2015
The utility of Li and Li isotopes in Earth and planetary science is discussed in this chapter, with a particular focus to major planetary bodies (Moon, Mars) and other inner Solar System pilgrims (Vesta) of which we are aware to have physical samples in our collections.

Barium isotope cosmochemistry and geochemistry

Science Bulletin, 2018
While the isotopic variations of barium were reported for the first time fourty years ago, the number of studies on barium isotopes significantly increased only after 2010. Barium isotope anomalies in meteorites have been successfully used to provide constraints about the origin of presolar SiC grains.

STUDIES IN EXPERIMENTAL ORGANIC COSMOCHEMISTRY

Annals of the New York Academy of Sciences, 1963
Organic synthesis processes, which may have occurred in the primitive earth atmosphere or in comets, produced in the laboratory by methods of electric discharge, uv light and ionizing ...

Meteorites and Cosmochemistry

1982
The study of meteorites is important for a number of reasons but three aspects are of particular significance. On the one hand they represent, along with lunar samples, the only extraterrestrial material available for detailed laboratory study. As such they provide an important window on the chemistry of the solar system, beyond what is directly ...
