Size Constraints for the Pre-atmospheric Parent Bodies of Ordinary Chondrites
Juan A. Sanchez, David C. Cantillo, Adam Battle +7
The study of S-complex near-Earth objects (NEOs), the parent bodies of ordinary chondrites, has shown that they are dominated by asteroids with LL chondrite-like compositions. This…
Chondrite Parent Bodies as Escaped Satellites of Proto-Planetary Embryos
Harold F. Levison, Rogerio Deienno, Kevin J. Walsh +4
Chondrites are composed of formerly partially molten material, known as chondrules, surrounded by fine-grained matrix. They date from the earliest times in Solar System history. Ho…
The fragility of the Uranian moons during the giant planet instability
Matthew S. Clement, Nathan A. Kaib, Andre Izidoro +1
It is thought that, sometime after their formation, the solar system's giant planets experienced a dynamical instability that caused their orbits to excite, diverge, and ejected on…
Terrestrial Planet Formation from Two Source Reservoirs
David Nesvorny, Alessandro Morbidelli, William F. Bottke +2
This work describes new dynamical simulations of terrestrial planet formation. The simulations started at the protoplanetary disk stage, when planetesimals formed and accreted into…
Size-Frequency Distribution of Terrestrial Leftover Planetesimals and S-complex Implanted Asteroids
Rogerio Deienno, Andre Izidoro, David Nesvorny +3
The isotopic composition of meteorites linked to S-complex asteroids has been used to suggest that these asteroids originated in the terrestrial planet's region, i.e., within 1.5 a…
Orbital and absolute magnitude distribution of Hilda population
David Vokrouhlický, David Nesvorný, Miroslav Brož +4
The Hilda population of asteroids is located in a large orbital zone of long-term stability associated with the Jupiter J3/2 mean motion resonance. They are a sister population of…
