The isotopic composition of meteorites and terrestrial planets holds important clues about
the earliest history of the Solar System and the processes of planet formation. Recent work …

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

Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2
spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide …

Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

Context. The explosion of observational data on exoplanets gives many constraints on
theoretical models of planet formation and evolution. Observational data probe very large …

We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients
to build habitable worlds like Earth, but their origin and evolution on terrestrial planets …

Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

Nucleosynthetic isotope variability among Solar System objects is often used to probe the
genetic relationship between meteorite groups and the rocky planets (Mercury, Venus, Earth …

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type
(CI) chondrites are distinct from other carbonaceous chondrites, which has led to the …
