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 ...

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, 2018While 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, 1963Organic 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 ...

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 ...

Planetary and Space Science, 2001
Abstract Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement—both polarities in subsequent analyses, (b) high lateral ...

The Cosmochemistry of Boron Isotopes
2017The boron elemental abundances and isotopic compositions in the universe and constituents (stars, interstellar medium and the Solar System material) within it have important implications for the astrophysical origins of this element. Astronomical observations and laboratory analysis have revealed that despite a significant difference in boron ...
