Origin of nucleosynthetic isotope variability in the NC reservoir: Evidence from Ti, Cr, and Mo isotopes

Elias Wölfer, Christoph Burkhardt, Gerrit Budde +3

Nucleosynthetic isotope anomalies allow distinguishing between non-carbonaceous (NC) and carbonaceous (CC) type meteorites, and have revealed correlated isotope variations especial…

Origin of moderately volatile elements in Earth inferred from mass-dependent Ge isotope variations among chondrites

Elias Wölfer, Christoph Burkhardt, Francis Nimmo +1

The bulk silicate Earth (BSE) is depleted in moderately volatile elements, indicating Earth formed from a mixture of volatile-rich and -poor materials. To better constrain the orig…

Comparison of the earliest NC and CC planetesimals: Evidence from ungrouped iron meteorites

Fridolin Spitzer, Christoph Burkhardt, Thomas S. Kruijer +1

Isotope anomalies in meteorites reveal a fundamental dichotomy between non-carbonaceous- (NC) and carbonaceous-type (CC) planetary bodies. Until now, this dichotomy is established…

Did the terrestrial planets of the Solar System form by pebble accretion?

Alessandro Morbidelli, Thorsten Kleine, Francis Nimmo

The dominant accretion process leading to the formation of the terrestrial planets of the Solar System is a subject of intense scientific debate. Two radically different scenarios…

Mechanisms and timing of carbonaceous chondrite delivery to the Earth

Francis Nimmo, Thorsten Kleine, Alessandro Morbidelli +1

The nucleosynthetic isotope signatures of meteorites and the bulk silicate Earth (BSE) indicate that Earth consists of a mixture of "carbonaceous" (CC) and "non-carbonaceous" (NC)…

Condensate evolution in the solar nebula inferred from combined Cr, Ti, and O isotope analyses of amoeboid olivine aggregates

Christian A. Jansen, Christoph Burkhardt, Yves Marrocchi +3

Refractory inclusions in chondritic meteorites, namely amoeboid olivine aggregates (AOAs) and Ca-Al-rich inclusions (CAIs), are among the first solids to have formed in the solar s…

Contemporary formation of early solar system planetesimals at two distinct radial locations

Alessandro Morbidelli, Kevin Baillie, Konstantin Batygin +4

The formation of planetesimals is expected to occur via particle-gas instabilities that concentrate dust into self-gravitating clumps. Triggering these instabilities requires the p…
