Distant TNO Inclinations as a Constraint on Primordial Cluster Perturbations in the Presence of Planet Nine
Avni Bansal, Ian Brunton, Konstantin Batygin +2
The Sun was almost certainly born in a stellar cluster, implying some degree of external forcing from neighboring stars during the Solar System's infancy. Published estimates of th…
A Census Before Rubin of Asteroid Families in the Main Belt
David Nesvorny
A collisional family is a collection of >km-size asteroid fragments produced by a large scale collision between asteroids. Here we cataloged 335 notable collisional families in the…
Discovery of 63 New Young Asteroid Families
David Nesvorny, David Vokrouhlicky, Miroslav Broz +1
We searched for young asteroid families -- those with ages t_age < 10 Myr and at least three members -- using the proper element catalog from Nesvorny et al. (2024). Our approach e…
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…
Predictions of the LSST Solar System Yield: Near-Earth Objects, Main Belt Asteroids, Jupiter Trojans, and Trans-Neptunian Objects
Jacob A. Kurlander, Pedro H. Bernardinelli, Megan E. Schwamb +18
The NSF-DOE Vera C. Rubin Observatory is a new 8m-class survey facility presently being commissioned in Chile, expected to begin the 10yr-long Legacy Survey of Space and Time (LSST…
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…
Orbit, meteoroid size, and cosmic ray exposure history of the Aguas Zarcas CM2 breccia
Peter Jenniskens, Gerardo J. Soto, Gabriel Goncalves Silva +21
The Aguas Zarcas (Costa Rica) CM2 carbonaceous chondrite fell during night time in April 2019. Security and dashboard camera video of the meteor were analyzed to provide a trajecto…
Dust-void evolution driven by turbulent dust flux can induce runaway migration of Earth-mass planets
R. O. Chametla, O. Chrenko, F. S. Masset +2
Torques from asymmetric dust structures (so-called dust-void and filamentary structures) formed around low-mass planets embedded in a non turbulent dust-gas disk can exceed the tor…
Compositional Outcomes of Earth Formation from a Narrow Ring
Katherine I. Dale, Alessandro Morbidelli, David C. Rubie +1
We address Earth formation from an elemental perspective, using a method similar to Rubie et al. (2015) but with updates from Dale et al. (2023) to simulate the chemical evolution…
A pre-flyby view on the origin of asteroid Donaldjohanson, a target of the NASA Lucy mission
Simone Marchi, David Vokrouhlický, David Nesvorný +3
The NASA Lucy mission is scheduled to fly-by the main belt asteroid (52246) Donaldjohanson on April 20, 2025. Donaldjohanson (DJ hereafter) is a member of the primitive (C-type cla…
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…
A Spiral Structure in the Inner Oort Cloud
David Nesvorny, Luke Dones, David Vokrouhlicky +5
As the Galactic tide acts to decouple bodies from the scattered disk it creates a spiral structure in physical space that is roughly 15,000 au in length. The spiral is long-lived a…
Occultation constraints on solar system formation models
Marc W. Buie, John M. Keller, David Nesvorny +1
The process by which a system of non-luminous bodies form around a star is fundamental to understanding the origins of our own solar system and how it fits into the context of othe…
Reassessing the origin and evolution of Ecliptic Comets in the Planet-9 Scenario
Rafael Ribeiro, Andre Izidoro, Alessandro Morbidelli +2
A group of newly observed extreme trans-Neptunian objects exhibit unexpected orbital confinement, characterized by the alignment of orbital angular momentum vectors and apsidal lin…
Mechanisms and timing of carbonaceous chondrite delivery to the Earth
Francis Nimmo, Thorsten Kleine, Alessandro Morbidelli +1
The nucleosynthetic isotope signatures of meteorites and the bulk silicate Earth (BSE) indicate that Earth consists of a mixture of "carbonaceous" (CC) and "non-carbonaceous" (NC)…
The Exoplanet Edge: Planets Don't Induce Observable TTVs with a Dominant TTV Period Faster than Half their Orbital Period
Daniel A. Yahalomi, David Kipping, Eric Agol +1
Transit timing variations (TTVs) are observed for exoplanets at a range of amplitudes and periods, yielding an ostensibly degenerate forest of possible explanations. We offer some…
On the early thermal processing of planetesimals during and after the giant planet instability
A. Gkotsinas, D. Nesvorny, A. Guilbert-Lepoutre +2
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets' dynamical i…
Nitrogen Loss from Pluto's Birth to the Present Day via Atmospheric Escape, Photochemical Destruction, and Impact Erosion
Perianne E. Johnson, Leslie A. Young, David Nesvorny +1
We estimate the loss of nitrogen from Pluto over its lifetime, including the giant planet instability period, which we term the "Wild Years." We analyze the orbital migration of 53…
Catalog of Proper Orbits for 1.25 Million Main Belt Asteroids and Discovery of 136 New Collisional Families
David Nesvorny, Fernando Roig, David Vokrouhlicky +1
The proper elements of asteroids are obtained from the instantaneous orbital elements by removing periodic oscillations produced by gravitational interactions with planets. They ar…
The Dynamical Origins of the Dark Comets and a Proposed Evolutionary Track
Aster G. Taylor, Jordan K. Steckloff, Darryl Z. Seligman +5
So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that exhibit nongravitational accelerations inconsistent with radiative effects. These objects…
EL meteorites do date the giant planet instability
Chrysa Avdellidou, Marco Delbo, David Nesvorny +2
In our recent work, we combined dynamical simulations, meteoritic data and thermal models as well as asteroid observations to argue that the current parent body of the EL meteorite…
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…
Terrestrial planet formation from a ring: long-term simulations accounting for the giant planet instability
J. M. Y. Woo, D. Nesvorny, J. Scora +1
The process leading to the formation of the terrestrial planet remains elusive. In a previous publication, we have shown that, if the first generation of planetesimals forms in a r…
