How to form planetesimals from mm-sized chondrules and chondrule aggregates

D Carrera, A Johansen, MB Davies - Astronomy & Astrophysics, 2015 - aanda.org
The size distribution of asteroids and Kuiper belt objects in the solar system is difficult to
reconcile with a bottom-up formation scenario due to the observed scarcity of objects smaller …

The early Solar System and its meteoritical witnesses

E Jacquet, C Dullemond, J Drążkowska… - Space Science Reviews, 2024 - Springer
Meteorites, and in particular primitive meteorites (chondrites), are irreplaceable probes of
the solar protoplanetary disk. We review their essential properties and endeavour to place …

The bouncing barrier revisited: Impact on key planet formation processes and observational signatures

C Dominik, CP Dullemond - Astronomy & Astrophysics, 2024 - aanda.org
Context. A leading paradigm in planet formation is currently the streaming instability and
pebble accretion scenario. Notably, dust must grow into sizes in a specific regime of Stokes …

Streaming instability of multiple particle species in protoplanetary disks

N Schaffer, CC Yang, A Johansen - Astronomy & Astrophysics, 2018 - aanda.org
The radial drift and diffusion of dust particles in protoplanetary disks affect both the opacity
and temperature of such disks, as well as the location and timing of planetesimal formation …

The coma dust of comet C/2013 US10 (Catalina): A window into carbon in the solar system

Collisions and compositional variability in chondrule-forming events

E Jacquet - Geochimica et Cosmochimica Acta, 2021 - Elsevier
Compound chondrules, ie chondrules fused together, make a powerful probe of the density
and compositional diversity in chondrule-forming environments, but their abundance among …

Formation of chondrule fine‐grained rims from local nebular reservoirs

GA Pinto, Y Marrocchi, E Jacquet… - Meteoritics & Planetary …, 2022 - Wiley Online Library
Chondrules are commonly surrounded by fine‐grained rims (FGRs) whose origin remains
highly debated; both nebular and parent body settings are generally proposed. Deciphering …

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

E Jacquet, O Alard, M Gounelle - Geochimica et Cosmochimica Acta, 2015 - Elsevier
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 …
