Non-equilibrium condensation of the first Solar System solids
Sebastien Charnoz, Jérome Aleon, Marc Chaussidon +3
Primitive meteorites (chondrites) consist of an out-of-equilibrium assemblage of minerals formed during the assembling of our Solar Nebula. The conditions under which their precurs…
A Collective Trigger for Widespread Planetesimal Formation Revealed by Accretion Ages
James Bryson, Hannah Sanderson, Francis Nimmo +4
The formation of planetesimals was an integral part of the cascading series of processes that built the terrestrial planets. To illuminate planetesimal formation, here we develop a…
The refractory-to-ice ratio in comet 67P: implications on the composition of the comet-forming region of the protoplanetary disk
Raphael Marschall, Alessandro Morbidelli, Yves Marrocchi
Comets, asteroids, and other small bodies are thought to be remnants of the original planetesimal population of the Solar System. As such, their physical, chemical, and isotopic pr…
The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites
Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88
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 sugge…
Formation and evolution of a protoplanetary disk: combining observations, simulations and cosmochemical constraints
Alessandro Morbidelli, Yves Marrocchi, Adnan Ali Ahmad +12
We present a plausible and coherent view of the evolution of the protosolar disk that is consistent with the cosmochemical constraints and compatible with observations of other pro…
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…
