Binary formation in planetesimal disks. II. Planetesimals with a mass spectrum [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2014
Abstract Many massive objects have been found in the outer region of the solar system. How they were formed and evolved has not been well understood, although there have been intensive studies of the accretion process of terrestrial planets. One of the mysteries is the existence of binary planetesimals with near-equal mass components and

The Last Stages of Terrestrial Planet Formation: Dynamical Friction and the Late Veneer [PDF]

open access: yes, 2012
The final stage of terrestrial planet formation consists of the cleanup of residual planetesimals after the giant impact phase. Dynamically, a residual planetesimal population is needed to damp the high eccentricities of the terrestrial planets after the

A Long‐Lived Planetesimal Dynamo Powered by Core Crystallization

open access: yesGeophysical Research Letters, 2021
The existence of numerous iron meteorite groups indicates that some planetesimals underwent melting that led to metal‐silicate segregation, sometimes producing metallic cores.

Wind-shearing in gaseous protoplanetary disks

open access: yes, 2010
One of the first stages of planet formation is the growth of small planetesimals and their accumulation into large planetesimals and planetary embryos. This early stage occurs much before the dispersal of most of the gas from the protoplanetary disk. Due

Dust-to-gas ratio resurgence in circumstellar disks due to the formation of giant planets: the case of HD 163296 [PDF]

open access: yes, 2019
The amount of dust present in circumstellar disks is expected to steadily decrease with age due to the growth from micron-sized particles to planetesimals and planets. Mature circumstellar disks, however, can be observed to contain significant amounts of

Self-stirring of debris discs by planetesimals formed by pebble concentration [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
When a protoplanetary disc loses gas, it leaves behind planets and one or more planetesimal belts. The belts get dynamically excited, either by planets ('planet stirring') or by embedded big planetesimals ('self-stirring').

The Formation of Jupiter, the Jovian Early Bombardment and the Delivery of Water to the Asteroid Belt: The Case of (4) Vesta

open access: yesLife, 2014
The asteroid (4) Vesta, parent body of the Howardite-Eucrite-Diogenite meteorites, is one of the first bodies that formed, mostly from volatile-depleted material, in the Solar System. The Dawn mission recently provided evidence that hydrated material was

Planetesimal Initial Mass Functions Following Diffusion-regulated Gravitational Collapse

open access: yesThe Astrophysical Journal, 2023
The initial mass function (IMF) of planetesimals is of key importance for understanding the initial stages of planet formation, yet theoretical predictions so far have been insufficient in explaining the variety of IMFs found in simulations.
