Challenges in planet formation

  title={Challenges in planet formation},
  author={A. Morbidelli and S. Raymond},
  journal={Journal of Geophysical Research},
Over the past two decades, large strides have been made in the field of planet formation. Yet fundamental questions remain. Here we review our state of understanding of five fundamental bottlenecks in planet formation. These are the following: (1) the structure and evolution of protoplanetary disks; (2) the growth of the first planetesimals; (3) orbital migration driven by interactions between protoplanets and gaseous disk; (4) the origin of the Solar System's orbital architecture; and (5) the… Expand

Formation of Terrestrial Planets
The past decade has seen major progress in our understanding of terrestrial planet formation. Yet key questions remain. In this review we first address the growth of 100 km-scale planetesimals as aExpand
Planet formation: key mechanisms and global models
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 blocks. This reviewExpand
Topical Problems in the Theory of Planet Formation: Formation of Planetesimals
We consider the history of the development of the theory of the formation of the Earth and planets over 70 years with special emphasis placed on the development of this theory at the SchmidtExpand
A hypothesis for the rapid formation of planets
The discovery of 1I/`Oumuamua confirmed that planetesimals must exist in great numbers in interstellar space. Originally generated during planet formation, they are scattered from their originalExpand
Can narrow discs in the inner Solar system explain the four terrestrial planets?
A successful solar system model must reproduce the four terrestrial planets. Here, we focus on 1) the likelihood of forming Mercury and the four terrestrial planets in the same system (a 4-P system);Expand
Formation of Giant Planet Satellites
Recent analyses have shown that the concluding stages of giant planet formation are accompanied by the development of large-scale meridional flow of gas inside the planetary Hill sphere. ThisExpand
The planet nine hypothesis
Over the course of the past two decades, observational surveys have unveiled the intricate orbital structure of the Kuiper Belt, a field of icy bodies orbiting the Sun beyond Neptune. In addition toExpand
Dynamical rearrangement of super-Earths during disk dispersal II. Assessment of the magnetospheric rebound model for planet formation scenarios
Context.The Kepler mission has provided a large sample to statistically analyze the orbital properties of the super-Earth planets. We hypothesize that these planets formed early and consider theExpand
The contribution of the ARIEL space mission to the study of planetary formation
The most outstanding open questions concerning the way planets form and the mechanisms that contribute to create habitable environments that the compositional information gathered by ARIEL will allow to tackle are reviewed. Expand
Dynamical rearrangement of super-Earths during disk dispersal - I. Outline of the magnetospheric rebound model
Context. The Kepler mission has discovered that close-in super-Earth planets are common around solar-type stars. They are often seen together in multiplanetary systems, but their period ratios do notExpand


Giant Planet Formation, Evolution, and Internal Structure
The large number of detected giant exoplanets offers the opportunity to improve our understanding of the formation mechanism, evolution, and interior structure of gas giant planets. The two mainExpand
Building Terrestrial Planets
This article reviews our current understanding of terrestrial planet formation. The focus is on computer simulations of the dynamical aspects of the accretion process. Throughout the review, weExpand
Formation of Protoplanet Systems and Diversity of Planetary Systems
We investigate the formation of protoplanet systems from planetesimal disks by global (N = 5000 and 10,000 and 0.5 AU 2. The growth timescale increases with a but decreases with Σ1. Based on theExpand
Observable consequences of planet formation models in systems with close-in terrestrial planets
To date, two planetary systems have been discovered with close-in, terrestrial-mass planets (� 5‐10 M ⊕ ). Many more such discoveries are anticipated in the coming years with radial velocity andExpand
Vulcan Planets: Inside-Out Formation of the Innermost Super-Earths
The compact multi-transiting systems discovered by Kepler challenge traditional planet formation theories. These fall into two broad classes: (1) formation further out followed by migration; (2)Expand
Dust Evolution and the Formation of Planetesimals
The solid content of circumstellar disks is inherited from the interstellar medium: dust particles of at most a micrometer in size. Protoplanetary disks are the environment where these dust grainsExpand
Terrestrial Planet Formation at Home and Abroad
We review the state of the field of terrestrial planet formation with the goal of understanding the formation of the inner Solar System and low-mass exoplanets. We review the dynamics and timescalesExpand
Models of giant planet formation with migration and disc evolution
We present a new model of giant planet formation that extends the core-accretion model of Pollack et al. (1996, Icarus, 124, 62) to include migration, disc evolution and gap formation. We show thatExpand
The Dispersal of Protoplanetary Disks
Protoplanetary disks are the sites of planet formation, and the evolution and eventual dispersal of these disks strongly influences the formation of planetary systems. Disk evolution during theExpand
Building the terrestrial planets: Constrained accretion in the inner Solar System
Abstract To date, no accretion model has succeeded in reproducing all observed constraints in the inner Solar System. These constraints include: (1) the orbits, in particular the smallExpand
