The timing of delivery and the types of body that contributed volatiles to the terrestrial planets
remain highly debated,. For example, it is unknown if differentiated bodies, such as that …

Ureilite meteorites are arguably our only large suite of samples from the mantle of a dwarf
planet and typically contain greater abundances of diamond than any known rock. Some …

The fate of highly volatile elements (H, C, F, Cl and S) during planetary accretion and
differentiation is debated. Recent analyses of water in non-carbonaceous chondrites (RC …

We present the results of melting experiments on a suite of carbonaceous and ordinary
chondritic compositions (CV, CM, CI, H and LL) performed at low pressure (0.1–13.1 MPa) …

Abstract On October 7, 2008, the asteroid 2008 TC3 exploded as it entered the Earth's
atmosphere, producing significant dust (in the atmosphere) and delivering thousands of …

Buckminsterfullerene, C 60, is the largest molecule observed to date in interstellar and
circumstellar environments. The mechanism of formation of this molecule is actively …

Carbon aggregates from two differently shocked ureilites were analyzed to gain insight into
the shock transformation of graphite to diamond in ureilites, which happened when the …

We report the first Ni and Cr stable isotope data for ureilite meteorites that are the mantle
residue of a carbon‐rich differentiated planet. Ureilites have similar Ni stable isotope …

Abstract Acapulcoites-lodranites, ureilites, brachinites, brachinite-like achondrites and
winonaites are the main groups of primitive achondrites. They are variably depleted in …

Here, two of a range of possible models are explored that assume that:(i) two of the main
chondritic components (chondrules and refractory inclusions) dominated the Earth's building …
