Abstract— In the primordial solar system, the most plausible sources of the water accreted by the Earth were in the outer asteroid belt, in the giant planet regions, and in the Kuiper Belt. We…

Abstract— We show that at the end of the main accretional period of the terrestrial planets, a few percent of the initial planetesimal population in the 1–2 AU zone is left on highly‐inclined orbits…
Meteoritic Diversity and Planetesimal Formation

Meteorite parent bodies vary widely in composition and structure even though they all formed in the same protoplanetary nebula over a limited range of time and space. Nebula material underwent…
Planet Formation: An Optimized Population-synthesis Approach
- J. Chambers

- 9 August 2018
The physics of planet formation is investigated using a population synthesis approach. We develop a simple model for planetary growth including pebble and gas accretion, as well as orbital migration…
Steamworlds: Atmospheric Structure and Critical Mass of Planets Accreting Icy Pebbles
- J. Chambers
- Physics, Geology
- 9 October 2017
In the core accretion model, gas-giant planets first form a solid core, which then accretes gas from a protoplanetary disk when the core exceeds a critical mass. Here, we model the atmosphere of a…
FIVE NEW TRANSIT EPOCHS OF THE EXOPLANET OGLE-TR-111b

We report five new transit epochs of the extrasolar planet OGLE-TR-111b, observed in the v-HIGH and Bessell I bands with the FORS1 and FORS2 at the ESO Very Large Telescope between 2008 April and…
Rapid Formation of Jupiter and Wide-orbit Exoplanets in Disks with Pressure Bumps

- 21 April 2021
The formation of gas-giant planets within the lifetime of a protoplanetary disk is challenging especially far from a star. A promising model for the rapid formation of giant-planet cores is pebble…
