Planetesimal Accretion at Short Orbital Periods

open access: yesThe Astrophysical Journal, 2023
Formation models in which terrestrial bodies grow via the pairwise accretion of planetesimals have been reasonably successful at reproducing the general properties of the Solar System, including small-body populations. However, planetesimal accretion has

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

Kozai effect on planetesimal accretion in highly inclined binaries

open access: yesEPJ Web of Conferences, 2011
Planet formation in highly inclined binaries is a complex issue. The Kozai mechanism plays an important role in this situation, since it will lead to high eccentricity and high relative impact velocity of planetesimals, thus hinder the planetesimal ...

Numerical simulations for terrestrial planets formation

open access: yesEPJ Web of Conferences, 2011
We investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated.

The unexpected narrowness of eccentric debris rings: a sign of eccentricity during the protoplanetary disc phase [PDF]

open access: yesRoyal Society Open Science, 2020
This paper shows that the eccentric debris rings seen around the stars Fomalhaut and HD 202628 are narrower than expected in the standard eccentric planet perturbation scenario (sometimes referred to as ‘pericentre glow’). The standard scenario posits an

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

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.
