Dynamical evolution of the early solar system

D Nesvorný - Annual Review of Astronomy and Astrophysics, 2018 - annualreviews.org
Several properties of the Solar System, including the wide radial spacing of the giant
planets, can be explained if planets radially migrated by exchanging orbital energy and …

A low mass for Mars from Jupiter's early gas-driven migration

KJ Walsh, A Morbidelli, SN Raymond, DP O'Brien… - Nature, 2011 - nature.com
Jupiter and Saturn formed in a few million years (ref.) from a gas-dominated protoplanetary
disk, and were susceptible to gas-driven migration of their orbits on timescales of only∼ …

Analysis of impact crater populations and the geochronology of planetary surfaces in the inner solar system

CI Fassett - Journal of Geophysical Research: Planets, 2016 - Wiley Online Library
Analyzing the density of impact craters on planetary surfaces is the only known technique for
learning their ages remotely. As a result, crater statistics have been widely analyzed on the …

Origin of water in the inner Solar System: Planetesimals scattered inward during Jupiter and Saturn's rapid gas accretion

SN Raymond, A Izidoro - Icarus, 2017 - Elsevier
There is a long-standing debate regarding the origin of the terrestrial planets' water as well
as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a …

Earth's impact events through geologic time: a list of recommended ages for terrestrial impact structures and deposits

M Schmieder, DA Kring - Astrobiology, 2020 - liebertpub.com
This article presents a current (as of September 2019) list of recommended ages for proven
terrestrial impact structures (n= 200) and deposits (n= 46) sourced from the primary …

An Archaean heavy bombardment from a destabilized extension of the asteroid belt

WF Bottke, D Vokrouhlický, D Minton, D Nesvorný… - Nature, 2012 - nature.com
The barrage of comets and asteroids that produced many young lunar basins (craters over
300 kilometres in diameter) has frequently been called the Late Heavy Bombardment (LHB) …

Mars' growth stunted by an early giant planet instability

MS Clement, NA Kaib, SN Raymond, KJ Walsh - Icarus, 2018 - Elsevier
Many dynamical aspects of the solar system can be explained by the outer planets
experiencing a period of orbital instability sometimes called the Nice Model. Though often …

Crater degradation on the lunar maria: Topographic diffusion and the rate of erosion on the Moon

CI Fassett, BJ Thomson - Journal of Geophysical Research …, 2014 - Wiley Online Library
Landscape evolution on the Moon is dominated by impact cratering in the post‐maria
period. In this study, we mapped 800 m to 5 km diameter craters on> 30% of the lunar maria …

The link between planetary systems, dusty white dwarfs, and metal-polluted white dwarfs

JH Debes, KJ Walsh, C Stark - The Astrophysical Journal, 2012 - iopscience.iop.org
It has long been suspected that metal-polluted white dwarfs (types DAZ, DBZ, and DZ) and
white dwarfs with dusty disks possess planetary systems, but a specific physical mechanism …

The empty primordial asteroid belt

SN Raymond, A Izidoro - Science advances, 2017 - science.org
The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated,
with S-types dominating the inner belt and C-types the outer belt. It is generally assumed …
