The Bulk Densities of Small Solar System Bodies as a Probe of Planetesimal Formation

The Astrophysical Journal
Constraining the formation processes of small solar system bodies is crucial for gaining insights into planetesimal formation. Their bulk densities, determined by their compressive strengths, offer valuable information about their formation history.

Planetesimal-driven planet migration in the presence of a gas disk

, 2010
We report here on an extension of a previous study by Kirsh et al. (2009) of planetesimal-driven migration using our N-body code SyMBA (Duncan et al., 1998). The previous work focused on the case of a single planet of mass Mem, immersed in a planetesimal

Using Venus, Earth, and Mars to Understand Exoplanet Volatile and Climate Evolution

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Venus, Earth, and Mars exhibit a wide range of interactions between their deep interiors, surfaces, lower and upper atmospheres, and the Sun, with commensurate variations in the nature of their atmospheres and evolution of their volatiles. By examining these worlds' characteristics and behavior, we can gain some understanding of the breadth of

Planet formation in slightly inclined binary systems

EPJ Web of Conferences, 2011
One of the major problems of planet formation in close binary systems, such as α Centauri AB, is the formation of planetary embryos or cores by mutual accretion of km-sized planetesimals.

N-body simulations of oligarchic growth of Mars: Implications for Hf-W chronology

, 2013
Dauphas and Pourmand (2011) [Nature 473, 489--492] estimated the accretion timescale of Mars to be 1.8 $^{+0.9}_{-1.0}$ Myr from the W isotopes of martian meteorites.

Accumulation of Dust on a Surface and the Subsequent Formation of Compact Aggregate Piles

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Dust aggregation is a prominent topic in space physics, yet the accumulation of dust on surfaces in airless environments remains poorly understood. It is commonly assumed that, during the initial stages of dust deposition, particles spread uniformly to form a monolayer.

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.

A statistical investigation into relationships between the IIE irons and the ordinary, F and “HH” chondrites

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.
Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,

Distribution of Captured Planetesimals in Circumplanetary Gas Disks and Implications for Accretion of Regular Satellites [PDF]

, 2017
Regular satellites of giant planets are formed by accretion of solid bodies in circumplanetary disks. Planetesimals that are moving on heliocentric orbits and are sufficiently large to be decoupled from the flow of the protoplanetary gas disk can be ...
