Neutron captures produce the vast majority of abundances of elements heavier than iron in
the Universe. Beyond the classical slow (s) and rapid (r) processes, there is observational …

The isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC)
meteorites indicates that meteorite parent bodies derive from two genetically distinct …

terrestrial rocks. By the year 1850, 18 elements had been identified in meteorites: carbon,
oxygen, sodium, magnesium, aluminum, silicon, phosphorous, sulfur, potassium, calcium …

“The Answer to the Great Question... Of Life, the Universe and Everything... Is... Forty-two,”
said Deep Thought, with infinite majesty and calm…“I checked it very thoroughly,” said the …

Earth is unique among the terrestrial planets in our solar system in having a fluid envelope
that fosters life. The secrets behind Earth's habitable climate are well-tuned cycles of carbon …

Nucleosynthetic isotope anomalies are powerful tracers to determine the provenance of
meteorites and their components, and to identify genetic links between these materials. Here …

Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …

We propose a new model of Earth's bulk composition based on enstatite chondrites (E-
chondrites), the only chondrite group isotopically identical to the Earth. This model allows a …

The excess of highly siderophile elements in the Earth's mantle is thought to reflect the
addition of primitive meteoritic material after core formation ceased,,,. This 'late veneer'either …

Material inherited from different nucleosynthesis sources imparts distinct isotopic signatures
to meteorites and terrestrial planets. These nucleosynthetic isotope anomalies have been …
