Planetesimal rings as the cause of the Solar System's planetary architecture
Astronomical observations reveal that protoplanetary disks around young stars commonly
have ring-and gap-like structures in their dust distributions. These features are associated …

Distinguishing the origin of asteroid (16) Psyche
The asteroid (16) Psyche may be the metal-rich remnant of a differentiated planetesimal, or it
may be a highly reduced, metal-rich asteroidal material that never differentiated. The NASA …

Planet formation: key mechanisms and global models
SN Raymond, A Morbidelli - … of Exoplanetary Systems: Lecture Notes of …, 2022 - Springer
Abstract Models of planet formation are built on underlying physical processes. In order to
make sense of the origin of the planets we must first understand the origin of their building …

Dynamical evidence for an early giant planet instability
The dynamical structure of the Solar System can be explained by a period of orbital
instability experienced by the giant planets. While a late instability was originally proposed …

Radial distribution of distant trans-Neptunian objects points to Sun's formation in a stellar cluster
Abstract The Scattered Disk Objects (SDOs) are a population of trans-Neptunian bodies with
semimajor axes 50< a≲ 1000 au and perihelion distances q≳ 30 au. The detached SDOs …

The early instability scenario: Terrestrial planet formation during the giant planet instability, and the effect of collisional fragmentation
The solar system's dynamical state can be explained by an orbital instability among the giant
planets. A recent model has proposed that the giant planet instability happened during …

The role of early giant-planet instability in terrestrial planet formation
The terrestrial planets are believed to have formed by violent collisions of tens of lunar-to

Isotopic trichotomy of main belt asteroids from implantation of outer solar system planetesimals
Recent analyses of samples from asteroid (162173) Ryugu returned by JAXA's Hayabusa2
mission suggest that Ryugu and CI chondrites formed in the same region of the …

Terrestrial planet formation from a ring
It has been long proposed that, if all the terrestrial planets form within a tiny ring of solid
material at around 1 AU, the concentrated mass-distance distribution of the current system …
