Prior work has found that a variety of terrestrial planetary compositions are expected to occur within known extrasolar planetary systems. However, such studies ignored the effects of giant planetExpand
Meteorites and the early solar system II
They range in size from microscopic particles to masses of many tons. The geologic diversity of asteroids and other rocky bodies of the solar system are displayed in the enormous variety of texturesExpand
Shape model and surface properties of the OSIRIS-REx target Asteroid (101955) Bennu from radar and lightcurve observations
We determine the three-dimensional shape of near-Earth Asteroid (101955) Bennu based on radar images and optical lightcurves. Bennu was observed both in 1999 at its discovery apparition, and in 2005Expand
Orbit and bulk density of the OSIRIS-REx target Asteroid (101955) Bennu
The target asteroid of the OSIRIS-REx asteroid sample return mission, (101955) Bennu (formerly 1999 RQ 36), is a half-kilometer near-Earth asteroid with an extraordinarily well constrained orbit. AnExpand
Supernova Olivine from Cometary Dust
An interplanetary dust particle contains a submicrometer crystalline silicate aggregate of probable supernova origin that has a pronounced enrichment in 18O/16O (13 times the solar value) and depletions in 29Si/28Si (<0.8 times solar), indicative of formation from a type II supernova. Expand
Making the Earth: Combining Dynamics and Chemistry in the Solar System
Abstract No terrestrial planet formation simulation completed to date has considered the detailed chemical composition of the planets produced. While many have considered possible water contents andExpand
OSIRIS-REx: Sample Return from Asteroid (101955) Bennu
In May of 2011, NASA selected the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) asteroid sample return mission as the third mission in the NewExpand
Sulfur chemistry with time-varying oxygen abundance during Solar System formation
Chemical models of solar nebula chemistry are presented which show the influence of progressive water depletion from the inner solar nebula. The main focus of this work is the equilibriumExpand
Thermal infrared observations and thermophysical characterization of OSIRIS-REx target asteroid (101955) Bennu
Abstract Near-Earth Asteroids (NEAs) have garnered ever increasing attention over the past few years due to the insights they offer into Solar System formation and evolution, the potential hazardExpand
Properties of rubble-pile asteroid (101955) Bennu from OSIRIS-REx imaging and thermal analysis
Establishing the abundance and physical properties of regolith and boulders on asteroids is crucial for understanding the formation and degradation mechanisms at work on their surfaces. Using imagesExpand
