Challenge in Arrokoth's single merger to achieve the shape's principal axis configuration
Ketan Kamat, Ryota Nakano, Masatoshi Hirabayashi
The cold-classical Kuiper Belt Object 486958 Arrokoth is a contact binary composed of two flattened lobes, Weeyo and Wenu, closely aligned along their principal axes, despite each…
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 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…
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…
The Perturbed Full Two-Body Problem: Application to Post-DART Didymos
Alex J. Meyer, Harrison F. Agrusa, Derek C. Richardson +19
With the successful impact of the NASA DART spacecraft in the Didymos-Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid…
Energy Dissipation in Synchronous Binary Asteroids
Alex J. Meyer, Daniel J. Scheeres, Harrison F. Agrusa +5
Synchronous binary asteroids can experience libration about their tidally-locked equilibrium, which will result in energy dissipation. This is an important topic to the Asteroid Im…
After DART: Using the first full-scale test of a kinetic impactor to inform a future planetary defense mission
Thomas S. Statler, Sabina D. Raducan, Olivier S. Barnouin +38
NASA's Double Asteroid Redirection Test (DART) is the first full-scale test of an asteroid deflection technology. Results from the hypervelocity kinetic impact and Earth-based obse…
Predictions for the Dynamical States of the Didymos System before and after the Planned DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +33
NASA's Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, around 23:14 UTC on 26 September 2022, causing a…
Active Main-Belt Asteroid (6478) Gault -- Constraint on Its Cohesive Strength and the Fate of Ejected Particles in the Solar System
Pierce M. Jackson, Ryota Nakano, Yaeji Kim +1
Active asteroid (6478) Gault sheds mass independent of location along its orbit. Rotational instability is considered to induce the observed activities. If this is the case, becaus…
Spin-driven evolution of asteroids' top-shapes at fast and slow spins seen from (101955) Bennu and (162173) Ryugu
Masatoshi Hirabayashi, Ryota Nakano, Eri Tatsumi +14
Proximity observations by OSIRIS-REx and Hayabusa2 provided clues on the shape evolution processes of the target asteroids, (101955) Bennu and (162173) Ryugu. Their oblate shapes w…
Mass shedding activities of Asteroid (3200) Phaethon enhanced by its rotation
Ryota Nakano, Masatoshi Hirabayashi
Asteroid (3200) Phaethon, a B-type asteroid, has been active during its perihelion passages. This asteroid is considered to be a source of the Geminid meteor stream. It is reported…
