Runaway Growth During Planet Formation: Explaining the Size Distribution of Large Kuiper Belt Objects [PDF]
, 2010 Runway growth is an important stage in planet formation during which large protoplanets form, while most of the initial mass remains in small planetesimals.

Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.

How to build Tatooine: reducing secular excitation in Kepler circumbinary planet formation
, 2012 Circumbinary planetary systems recently discovered by Kepler represent an important testbed for planet formation theories. Planetesimal growth in disks around binaries has been expected to be inhibited interior to ~10 AU by secular excitation of high ...

CONGLOMERATION OF KILOMETER-SIZED PLANETESIMALS [PDF]
The Astrophysical Journal, 2015 We study the efficiency of forming large bodies, starting from a sea of equal-sized planetesimals. This is likely one of the earlier steps of planet formation and relevant for the formation of the asteroid belt, the Kuiper belt and extra-solar debris disks.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a “late veneer” of impacts after the giant impact phase of planet formation. Estimates for total mass accretion during this period typically assume all HSEs delivered remain entrained in the mantle.

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.

Steady-state evolution of debris disks around A stars [PDF]
, 2007 In this paper a simple analytical model for the steady-state evolution of debris disks due to collisions is confronted with Spitzer observations of main sequence A stars.

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 720-738, April 2026.Abstract Mechanisms for metal core formation in rocky planetesimals and planetary embryos remain poorly constrained, in part due to complexities arising from immiscibility in core‐forming liquids at low pressures. To assess the pressure dependence of immiscibility and its role in protoplanetary differentiation, we performed experiments at 3 and 5 GPa ...

Evidence for the Disruption of a Planetary System During the Formation of the Helix Nebula
The Astronomical Journal, 2022 The persistence of planetary systems after their host stars evolve into their post-main-sequence phase is poorly constrained by observations. Many young white dwarf systems exhibit infrared excess emission and/or spectral absorption lines associated with
