Magnitude of stable iron isotope fractionation limited by multiple stages of terrestrial core formation
Gabriel Nathan, Seth A. Jacobson
One proposed mechanism for generating iron isotopic differences between planetary mantles and chondrites is metal-silicate equilibration during terrestrial core formation. Prior st…
Lithium Enrichment in a Subgiant Star with a Brown Dwarf Companion: A Planetary Engulfment Candidate
Brooke Kotten, Melinda Soares-Furtado, Ricardo Yarza +11
Theoretical models predict that subgiants within a narrow mass regime can retain detectable lithium enrichment signatures from planetary engulfment. We test this prediction using T…
Direct contact binary planetesimal formation from gravitational collapse
Jackson T. Barnes, Stephen R. Schwartz, Seth A. Jacobson
Bilobate contact binaries comprise a significant fraction of the relict Kuiper Belt, which includes the exemplary contact binary (486958) Arrokoth. The surfaces of its lobes contai…
Formation of Planetesimals in the Outer Solar System
Anders Johansen, Michele T. Bannister, Luke Dones +4
The Solar System hosts the most studied and best understood major and minor planetary bodies - and the only extraterrestrial bodies to have been visited by spacecraft. The Solar Sy…
Orbits of very distant asteroid satellites
K. Minker, B. Carry, F. Vachier +36
The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and…
Tungsten isotope evolution during Earth's formation and new constraints on the viability of accretion simulations
D. C. Rubie, K. I. Dale, G. Nathan +5
The Hf-W isotopic system is the reference chronometer for determining the chronology of Earth's accretion and differentiation. However, its results depend strongly on uncertain par…
BYORP and Dissipation in Binary Asteroids: Lessons from DART
Matija Ćuk, Harrison Agrusa, Rachel H. Cueva +10
The Near-Earth binary asteroid Didymos was the target of a planetary defense demonstration mission DART in September 2022. The smaller binary component, Dimorphos, was impacted by…
Forming Mercury from excited initial conditions
Jennifer Scora, Diana Valencia, Alessandro Morbidelli +1
Mercury is notoriously difficult to form in solar system simulations, due to its small mass and iron-rich composition. Smooth particle hydrodynamics simulations of collisions have…
Direct -body simulations of satellite formation around small asteroids: insights from DART's encounter with the Didymos system
Harrison F. Agrusa, Yun Zhang, Derek C. Richardson +18
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos-Dimorphos binary, which was the first small…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Momentum Transfer from the DART Mission Kinetic Impact on Asteroid Dimorphos
Andrew F. Cheng, Harrison F. Agrusa, Brent W. Barbee +66
The NASA Double Asteroid Redirection Test (DART) mission performed a kinetic impact on asteroid Dimorphos, the satellite of the binary asteroid (65803) Didymos, at 23:14 UTC on Sep…
Successful Kinetic Impact into an Asteroid for Planetary Defense
R. Terik Daly, Carolyn M. Ernst, Olivier S. Barnouin +98
While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional de…
The binary near-Earth asteroid (175706) 1996 FG3 - An observational constraint on its orbital evolution
P. Scheirich, P. Pravec, S. A. Jacobson +23
Using our photometric observations taken between 1996 and 2013 and other published data, we derived properties of the binary near-Earth asteroid (175706) 1996 FG3 including new mea…
