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…
Formation of Terrestrial Planets
Matthew S. Clement, Andre Izidoro, Sean N. Raymond +1
Our understanding of the process of terrestrial planet formation has grown markedly over the past 20 years, yet key questions remain. This review begins by first addressing the cri…
The Debiased Near-Earth Object Population from ATLAS Telescopes
Rogerio Deienno, Larry Denneau, David Nesvorný +7
This work is dedicated to debias the Near-Earth Objects (NEO) population based on observations from the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescopes. We have ap…
NEOMOD 3: The Debiased Size Distribution of Near Earth Objects
David Nesvorny, David Vokrouhlicky, Frank Shelly +9
Our previous model (NEOMOD2) for the orbital and absolute magnitude distribution of Near Earth Objects (NEOs) was calibrated on the Catalina Sky Survey observations between 2013 an…
Implantation of asteroids from the terrestrial planet region: The effect of the timing of the giant planet instability
Andre Izidoro, Rogerio Deienno, Sean N. Raymond +1
The dynamical architecture and compositional diversity of the asteroid belt strongly constrain planet formation models. Recent Solar System formation models have shown that the ast…
The link between Athor and EL meteorites does not constrain the timing of the giant planet instability
Andre Izidoro, Rogerio Deienno, Sean N. Raymond +1
The asteroid Athor, residing today in the inner main asteroid belt, has been recently associated as the source of EL enstatite meteorites to Earth. It has been argued that Athor fo…
Accretion and Uneven Depletion of the Main Asteroid Belt
Rogerio Deienno, David Nesvorny, Matthew S. Clement +3
The main asteroid belt (MAB) is known to be primarily composed of objects from two distinct taxonomic classes, generically defined here as S- and C-complex. The former probably ori…
Orbital and absolute magnitude distribution of Jupiter Trojans
David Vokrouhlický, David Nesvorný, Miroslav Brož +4
Jupiter Trojans (JTs) librate about the Lagrangian stationary centers L4 and L5 associated with this planet on a typically small-eccentricity and moderate-inclination heliocentric…
NEOMOD 2: An Updated Model of Near-Earth Objects from a Decade of Catalina Sky Survey Observations
David Nesvorny, David Vokrouhlicky, Frank Shelly +9
Catalina Sky Survey (CSS) is a major survey of Near-Earth Objects (NEOs). In a recent work, we used CSS observations from 2005-2012 to develop a new population model of NEOs (NEOMO…
Asteroids were born bigger: An implication of surface mass ablation during gas-assisted implantation into the asteroid belt
Rafael Ribeiro de Sousa, Andre Izidoro, Rogerio Deienno +1
The origins of carbonaceous asteroids in the asteroid belt is not fully understood. The leading hypothesis is that they were not born at their current location but instead implante…
Isotopic Trichotomy of Main Belt Asteroids from Implantation of Outer Solar System Planetesimals
David Nesvorny, Nicolas Dauphas, David Vokrouhlicky +2
Recent analyses of samples from asteroid (162173) Ryugu returned by JAXA's Hayabusa2 mission suggest that Ryugu and CI chondrites formed in the same region of the protoplanetary di…
A race against the clock: Constraining the timing of cometary bombardment relative to Earth's growth
Sarah Joiret, Sean N. Raymond, Guillaume Avice +3
Comets are considered a potential source of inner solar system volatiles, but the timing of this delivery relative to that of Earth's accretion is still poorly understood. Measurem…
The Collisional Evolution of the Primordial Kuiper Belt, Its Destabilized Population, and the Trojan Asteroids
William Bottke, David Vokrouhlicky, Raphael Marshall +6
The tumultuous early era of outer solar system evolution culminated when Neptune migrated across the primordial Kuiper belt (PKB) and triggered a dynamical instability among the gi…
NEOMOD: A New Orbital Distribution Model for Near Earth Objects
David Nesvorny, Rogerio Deienno, William F. Bottke +10
Near Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of aste…
Identification of a 4.3 billion year old asteroid family and planetesimal population in the Inner Main Belt
Salvatore Ferrone, Marco Delbo, Chrysa Avdellidou +4
After performing a reassessment of the known dynamical asteroid families in the inner main belt, we report a newly discovered ancient asteroid family with an estimated age of $4.3\…
Early Bombardment of the Moon: Connecting the Lunar Crater Record to the Terrestrial Planet Formation
David Nesvorny, Fernando V. Roig, David Vokrouhlicky +4
The lunar crater record features basins. The radiometric dating of Apollo samples indicates that the Imbrium basin formed relatively late -- from the planet formation per…
Formation of Lunar Basins from Impacts of Leftover Planetesimals
David Nesvorny, Fernando V. Roig, David Vokrouhlicky +4
The Moon holds important clues to the early evolution of the Solar System. Some 50 impact basins (crater diameter D>300 km) have been recognized on the lunar surface, implying that…
Rethinking the role of the giant planet instability in terrestrial planet formation models
Matthew S. Clement, Rogerio Deienno, Andre Izidoro
Advances in computing power and numerical methodologies over the past several decades sparked a prolific output of dynamical investigations of the late stages of terrestrial planet…
Implications of Jupiter Inward Gas-Driven Migration for the Inner Solar System
Rogerio Deienno, Andre Izidoro, Alessandro Morbidelli +2
The migration history of Jupiter in the sun's natal disk remains poorly constrained. Here we consider how Jupiter's migration affects small-body reservoirs and how this constrains…
