3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2623-2654, November 2025.Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

A Lagrangian Integrator for Planetary Accretion and Dynamics (LIPAD)
, 2012 We presented the first particle based, Lagrangian code that can follow the collisional/accretional/dynamical evolution of a large number of km-sized planetesimals through the entire growth process to become planets.

Rapid Formation of Saturn after Jupiter Completion
, 2012 We have investigated Saturn's core formation at a radial pressure maximum in a protoplanetary disk, which is created by gap opening by Jupiter. A core formed via planetesimal accretion induces the fragmentation of surrounding planetesimals, which ...

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick
The Astrophysical Journal LettersThe surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems.

Nebular water depletion as the cause of Jupiter's low oxygen abundance
, 2012 Motivated by recent spectroscopic observations suggesting that atmospheres of some extrasolar giant-planets are carbon-rich, i.e. carbon/oxygen ratio (C/O) $\ge$ 1, we find that the whole set of compositional data for Jupiter is consistent with the ...

The Multifaceted Planetesimal Formation Process [PDF]
, 2014 Accumulation of dust and ice particles into planetesimals is an important step in the planet formation process. Planetesimals are the seeds of both terrestrial planets and the solid cores of gas and ice giants forming by core accretion. Left-over planetesimals in the form of asteroids, trans-Neptunian objects and comets provide a unique record of the ...

Oligarchic Growth of Protoplanets in Planetesimal Rings
The Astrophysical JournalIn the standard planet formation scenario, planetesimals are assumed to form throughout the protoplanetary disk and to be smoothly distributed in the radial direction except for the snowline.

Silica-rich volcanism in the early solar system dated at 4.565 Ga
Nature Communications, 2018 Achondritic meteorites can record volcanism and crust formation on planetesimals in the early Solar System. Here, the authors date the Northwest Africa 11119 meteorite with an Al-Mg age of 4564.8 ± 0.3 Ma indicating that this is the earliest evidence of ...

26Al in the Early Solar System: Not so Unusual After All
, 2013 Recently acquired evidence shows that extrasolar asteroids exhibit over a factor of 100 variation in the iron to aluminum abundance ratio. This large range likely is a consequence of igneous differentiation that resulted from heating produced by ...
