A change of the rotation period of asteroid (65803) Didymos caused by the DART impact
Josef Durech, Petr Pravec, Masatoshi Hirabayashi +3
On 26 September 2022, the NASA Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the secondary component of the binary asteroid (65803)~Didymos. This experimen…
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…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
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…
The Dynamical State of the Didymos System Before and After the DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +50
NASA's Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the natural satellite of (65803) Didymos, on 2022 September 26, as a first successful test of kinetic…
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…
