Interstellar Ices as Carriers of Supernova Material to the Early Solar System
Martin Bizzarro, Martin Schiller, Jesper Holst +10
Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiti…
Hydrodynamical simulations of proto-Moon degassing
Gustavo Madeira, Leandro Esteves, Sebastien Charnoz +2
Similarities in the non-mass dependent isotopic composition of refractory elements with the bulk silicate Earth suggest that both the Earth and the Moon formed from the same materi…
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…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
Tidal pull of the Earth strips the proto-Moon of its volatiles
S. Charnoz, P. A. Sossi, Y-N Lee +7
Prevailing models for the formation of the Moon invoke a giant impact between a planetary embryo and the proto-Earth \citep{Canup_2004, Cuk_Stewart_2012}. Despite similarities in t…
Hybrid accretion of carbonaceous chondrites by radial transport across the Jupiter barrier
Elishevah van Kooten, Martin Schiller, Frederic Moynier +3
Understanding the origin of chondritic components and their accretion pathways is critical to unravel the magnitude of mass transport in the protoplanetary disk, the accretionary h…
Evidence for transient atmospheres during eruptive outgassing on the Moon
Elishevah van Kooten, Frédéric Moynier, James Day
Events following the giant impact formation of the Moon are thought to have led to volatile depletion and concurrent mass-dependent fractionation of the isotopes of moderately vola…
Mineralogy, chemistry and composition of organic compounds in the fresh carbonaceous chondrite Mukundpura: CM1 or CM2?
S. Potin, P. Beck, L. Bonal +7
We present here several laboratory analyses performed on the freshly fallen Mukundpura CM chondrite. Results of infrared transmission spectroscopy, thermogravimetry analysis and re…
Timing of thermal metamorphism in CM chondrites: implication for Ryugu and Bennu future sample return
Elsa Amsellem, Frédéric Moynier, Brandon Mahan +1
Carbonaceous chondrites are often considered potential contributors of water and other volatiles to terrestrial planets as most of them contain significant amounts of hydrous miner…
Zinc isotope analyses of singularly small samples (<5 ng Zn): investigating chondrule-matrix complementarity in Leoville
Elishevah van Kooten, Frederic Moynier
The potential complementarity between chondrules and matrix of chondrites, the Solar System's building blocks, is still a highly debated subject. Complementary superchrondritic com…
Some things special about NEAs: Geometric and environmental effects on the optical signatures of hydration
S. Potin, P. Beck, B. Schmitt +1
Here were report on a laboratory study aiming to reproduce specificities of near-Earth Asteroid. We study how the elevated surface temperature, their surface roughness (rock or reg…
Volatile loss following cooling and accretion of the Moon revealed by chromium isotopes
Paolo A. Sossi, Frédéric Moynier, Kirsten van Zuilen
Terrestrial and lunar rocks share chemical and isotopic similarities in refractory elements, suggestive of a common precursor. By contrast, the marked depletion of volatile element…
Chromium isotopic homogeneity between the Moon, the Earth, and enstatite chondrites
Berengere Mougel, Frederic Moynier, Christa Gopel
Among the elements exhibiting non-mass dependent isotopic variations in meteorites, chromium (Cr) has been central in arguing for an isotopic homogeneity between the Earth and the…
A history of violence: insights into post-accretionary heating in carbonaceous chondrites from volatile element abundances, Zn isotopes, and water contents
Brandon Mahan, Frederic Moynier, Pierre Beck +2
Carbonaceous chondrites (CCs) may have been the carriers of water, volatile and moderately volatile elements to Earth. Investigating the abundances of these elements, their relativ…
Gallium isotopic evidence for extensive volatile loss from the Moon during its formation
Chizu Kato, Frederic Moynier
The distribution and isotopic composition of volatile elements in planetary materials holds a key to the characterization of the early solar system and the Moon's formation. The Mo…
Early formation of planetary building blocks inferred from Pb isotopic ages of chondrules
Jean Bollard, James N. Connelly, Martin J. Whitehouse +6
The most abundant components of primitive meteorites (chondrites) are millimeter-sized glassy spherical chondrules formed by transient melting events in the solar protoplanetary di…
Early Solar System irradiation quantified by linked vanadium and beryllium isotope variations in meteorites
Paolo A. Sossi, Frederic Moynier, Marc Chaussidon +3
X-ray emission in young stellar objects (YSOs) is orders of magnitude more intense than in main sequence stars1,2, suggestive of cosmic ray irradiation of surrounding accretion dis…
Testing the chondrule-rich accretion model for planetary embryos using calcium isotopes
Elsa Amsellem, Frédéric Moynier, Emily A. Pringle +3
Understanding the composition of raw materials that formed the Earth is a crucial step towards understanding the formation of terrestrial planets and their bulk composition. Calciu…
