Building terrestrial planets

A Morbidelli, JI Lunine, DP O'Brien… - Annual Review of …, 2012 - annualreviews.org
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 …

Challenges in planet formation

A Morbidelli, SN Raymond - Journal of Geophysical Research …, 2016 - Wiley Online Library
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 …

Bifurcation of planetary building blocks during Solar System formation

T Lichtenberg, J Dra̧żkowska, M Schönbächler… - Science, 2021 - science.org
Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

Age of Jupiter inferred from the distinct genetics and formation times of meteorites

TS Kruijer, C Burkhardt, G Budde… - Proceedings of the …, 2017 - National Acad Sciences
The age of Jupiter, the largest planet in our Solar System, is still unknown. Gas-giant planet
formation likely involved the growth of large solid cores, followed by the accumulation of gas …

Planetesimal rings as the cause of the Solar System's planetary architecture

A Izidoro, R Dasgupta, SN Raymond, R Deienno… - Nature …, 2022 - nature.com
Astronomical observations reveal that protoplanetary disks around young stars commonly
have ring-and gap-like structures in their dust distributions. These features are associated …

Planet formation theory in the era of ALMA and Kepler: from pebbles to exoplanets

J Drazkowska, B Bitsch, M Lambrechts… - arXiv preprint arXiv …, 2022 - arxiv.org
Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our …

The growth of planets by pebble accretion in evolving protoplanetary discs

B Bitsch, M Lambrechts, A Johansen - Astronomy & Astrophysics, 2015 - aanda.org
The formation of planets depends on the underlying protoplanetary disc structure, which in
turn influences both the accretion and migration rates of embedded planets. The disc itself …

Framework for the architecture of exoplanetary systems-I. Four classes of planetary system architecture

L Mishra, Y Alibert, S Udry, C Mordasini - Astronomy & Astrophysics, 2023 - aanda.org
We present a novel, model-independent framework for studying the architecture of an
exoplanetary system at the system level. This framework allows us to characterise, quantify …

Make super-Earths, not Jupiters: Accreting nebular gas onto solid cores at 0.1 AU and beyond

EJ Lee, E Chiang, CW Ormel - The Astrophysical Journal, 2014 - iopscience.iop.org
Close-in super-Earths having radii 1–4 R⊕ may possess hydrogen atmospheres comprising
a few percent by mass of their rocky cores. We determine the conditions under which such …

Toward a deterministic model of planetary formation. I. A desert in the mass and semimajor axis distributions of extrasolar planets

S Ida, DNC Lin - The Astrophysical Journal, 2004 - iopscience.iop.org
In an attempt to develop a deterministic theory for planet formation, we examine the
accretion of cores of giant planets from planetesimals, gas accretion onto the cores, and …
