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…
Airfall on Comet 67P/Churyumov-Gerasimenko
B. J. R. Davidsson, S. Birch, G. A. Blake +11
We here study the transfer process of material from one hemisphere to the other (deposition of airfall material) on an active comet nucleus, specifically 67P/Churyumov-Gerasimenko.…
Rotation-induced granular motion on the secondary component of binary asteroids: Application to the DART impact on Dimorphos
Harrison Agrusa, Ronald Ballouz, Alex J. Meyer +6
NASA's Double Asteroid Redirection Test (DART) mission will kinetically impact Dimorphos, the secondary component of the Didymos binary asteroid system, which will excite Dimorphos…
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…
A LOOK at Outbursts of Comet C/2014 UN (Bernardinelli-Bernstein) Near 20 au
Michael S. P. Kelley, Rosita Kokotanekova, Carrie E. Holt +10
Cometary activity may be driven by ices with very low sublimation temperatures, such as carbon monoxide ice, which can sublimate at distances well beyond 20 au. This point is empha…
