3D analytical theory of the perturbed single-synchronous state. Application to the post-impact Didymos-Dimorphos system
Michalis Gaitanas, Christos Efthymiopoulos, Ioannis Gkolias +2
We develop the 3D generalization of the planar analytical theory presented in Gaitanas et. al., 2024, which deals with states slightly perturbed from the exact `single-synchronous…
