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 ...

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 ...

Cosmochemistry can be said to aim at constructing a quantitative and continuous history of chemical evolution of our universe starting from appearance of hydrogenic matter immediately after the Big Bang. While the main events of this history are embodied in stellar nucleosynthesis, the scope of the complete history is much larger.

Geochemistry and Cosmochemistry
The main advantage of Secondary Ionization Mass Spectrometry (SIMS) analysis of geological solids and rare samples from the Moon, Mars, asteroids, or comets lies in localized isotope ratio determination at high sensitivity, with minimal sample consumption, and with a wide dynamic range over many stable and radiogenic isotope systems.
