Are Thalassa and Despina in Resonance Lock with Neptune's Oscillations?
Matija Äuk, Harrison F. Agrusa, Marina BrozoviÄ +1
The two innermost moons of Neptune, Naiad and Thalassa, are currently in a 73:69 mean-motion resonance. This resonance relies on the large inclination of Naiad, and we estimate tha…
Dynamics of planetary rings under thermal forces
Wen-Han Zhou, Eiichiro Kokubo, Harrison Agrusa +5
Planetary rings provide natural laboratories for studying the fundamental processes that govern the evolution of planetary systems. However, several key features, such as the sharp…
Tidal disruptions of rubble piles: The case of Phobos
Harrison Agrusa, Patrick Michel
Many small satellites in the Solar System have sub-synchronous orbits, meaning their orbits are decaying due to tidal dissipation. Unless they have substantial material strength, t…
Gravitational scattering of ejecta in the Didymos system cannot explain the evolution of the binary's orbital period
Harrison Agrusa, Camille Chatenet
In the first few months following the DART impact on Dimorphos, it appears that the orbital period dropped by s in addition to the immediate min drop. This…
