The Influence of Central Body Tides on Catastrophic Disruptions of Close-in Planetary Satellites
Harrison Agrusa, Patrick Michel
We model the outcomes of catastrophic disruptions on small, gravity-dominated natural satellites, accounting for the tidal potential of the central body, which is neglected in clas…
Satellite formation around the largest asteroids
Kevin J. Walsh, Ronald-Louis Ballouz, Harrison F. Agrusa +3
Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13…
Confined tumbling state as the origin of the excess of slowly rotating asteroids
Wen-Han Zhou, Patrick Michel, Marco Delbo +4
The rotational distribution of asteroids as a function of their size is used {as a diagnostic of} their physical properties and evolution. Recent photometric surveys from the Gaia…
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…
A semi-analytical thermal model for craters with application to the crater-induced YORP effect
Wen-Han Zhou, Patrick Michel
Context. The YORP effect is the thermal torque generated by radiation from the surface of an asteroid. The effect is sensitive to surface topology, including small-scale roughness,…
The Yarkovsky effect on the long-term evolution of binary asteroids
Wen-Han Zhou, David Vokrouhlicky, Masanori Kanamaru +4
We explore the Yarkovsky effect on small binary asteroids. While significant attention has been given to the binary YORP effect, the Yarkovsky effect is often overlooked. We develo…
Physical properties of asteroid Dimorphos as derived from the DART impact
S. D. Raducan, M. Jutzi, A. F. Cheng +39
On September 26, 2022, NASA's Double Asteroid Redirection Test (DART) mission successfully impacted Dimorphos, the natural satellite of the binary near-Earth asteroid (65803) Didym…
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…
The Hera Radio Science Experiment at Didymos
Edoardo Gramigna, Riccardo Lasagni Manghi, Marco Zannoni +7
Hera represents the European Space Agency's inaugural planetary defense space mission and plays a pivotal role in the Asteroid Impact and Deflection Assessment international collab…
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…
