A 3D thermophysical model for binary asteroid systems: Application to the BYORP effect on (175706) 1996 FG3
Kya C. Sorli, Paul O. Hayne, Rachel H. Cueva +3
Differential heating and radiation on asymmetric asteroids can cause measurable changes in their rotation rates and spin axes, known as the YORP effect. In binary systems, such rad…
An Earth Encounter As the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH
Alex J Meyer, Oscar Fuentes-Muñoz, Ioannis Gkolias +4
Among binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown.…
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…
Apsidal Precession in Binary Asteroids
Alex J Meyer, Daniel J Scheeres
While the secondary in a binary asteroid plays an important role in the precession of the mutual orbit, this role has not been thoroughly studied. Given the complex spin-orbit coup…
