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…

Perihelion history and atmospheric survival as primary drivers of the Earth`s meteorite record

Patrick M. Shober, Hadrien A. R. Devillepoix, Jeremie Vaubaillon +7

Models predict that more than half of all impacting meteoroids should be carbonaceous, reflecting the abundance of carbon-rich asteroids in the main belt and near-Earth space. Yet…

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…

Martian meteorites reflectance and implications for rover missions

Lucia Mandon, Pierre Beck, Cathy Quantin-Nataf +7

In the next decade, two rovers will characterize in situ the mineralogy of rocks on Mars, using for the first time near-infrared reflectance spectrometers: SuperCam onboard the Mar…

Fingerprints of the protosolar cloud collapse in the Solar System I: Distribution of presolar short-lived Al

Francesco C. Pignatale, Emmanuel Jacquet, Marc Chaussidon +1

The short-lived radionuclide Al is widely used to determine the relative ages of chondrite components and timescales of physical and thermal events that attended the formati…

The fate of planetary cores in giant and ice-giant planets

S. Mazevet, R. Musella, F. Guyot

We used {\sl \textup{ab initio}} molecular dynamics simulations to calculate the high-pressure melting temperatures of the three potential core components. The planetary adiabats w…

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…

Chondrule Transport in Protoplanetary Disks

Aaron Z. Goldberg, James E. Owen, Emmanuel Jacquet

Chondrule formation remains one of the most elusive early Solar System events. Here, we take the novel approach of employing numerical simulations to investigate chondrule origin b…

Growth of calcium-aluminum-rich inclusions by coagulation and fragmentation in a turbulent protoplanetary disk: observations and modelisation

S. Charnoz, J. Aleon, N. Chaumard +2

Whereas it is generally accepted that calcium-aluminum-rich inclusions (CAIs) from chondritic meteorites formed in a hot environment in the solar protoplanetary disk, the condition…

Trace element geochemistry of ordinary chondrite chondrules: the type I/type II chondrule dichotomy

Emmanuel Jacquet, Olivier Alard, Matthieu Gounelle

We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for ca…

Trace element geochemistry of CR chondrite metal

Emmanuel Jacquet, Marine Paulhiac-Pison, Olivier Alard +2

We report trace element analyses by laser ablation inductively coupled plasma mass spectrometry of metal grains from 9 different CR chondrites, distinguishing grains from chondrule…

Chondrule trace element geochemistry at the mineral scale

Emmanuel Jacquet, Olivier Alard, Matthieu Gounelle

We report trace element analyses from mineral phases in chondrules from carbonaceous chondrites (Vigarano, Renazzo and Acfer 187), carried out by laser ablation inductively coupled…

Structure, composition, and location of organic matter in the enstatite chondrite Sahara 97096 (EH3)

Laurette Piani, FrançOis Robert, Olivier Beyssac +8

The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of analytical techniques. As the enstatite chon…

Water transport in protoplanetary disks and the hydrogen isotopic composition of chondrites

Emmanuel Jacquet, François Robert

The D/H ratios of carbonaceous chondrites, believed to reflect that of water in the inner early solar system, are intermediate between the protosolar value and that of most comets.…

On the aerodynamic redistribution of chondrite components in protoplanetary disks

Emmanuel Jacquet, Matthieu Gounelle, Sébastien Fromang

Despite being all roughly of solar composition, primitive meteorites (chondrites) present a diversity in their chemical, isotopic and petrographic properties, and in particular a f…

A Self-Consistent Reduced Model for Dusty Magnetorotationally Unstable Discs

Emmanuel Jacquet, Steven Balbus

The interaction between settling of dust grains and magnetorotational instability (MRI) turbulence in protoplanetary disks is analyzed. We use a reduced system of coupled ordinary…

On linear dust-gas streaming instabilities in protoplanetary discs

Emmanuel Jacquet, Steven A. Balbus, Henrik N. Latter

We revisit, via a very simplified set of equations, a linear streaming instability (technically an overstability), which is present in, and potentially important for, dusty protopl…

Radial transport of refractory inclusions and their preservation in the dead zone

Emmanuel Jacquet, Sébastien Fromang, Matthieu Gounelle

Calcium-aluminum-rich inclusions (CAIs) are the oldest solar system solids known in primitive meteorites (chondrites). They predate the other components by 1-2 Myr, and likely cond…
