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…
