DOI: 10.1016/j.actaastro.2020.02.006
Abstract: Abstract This paper investigates the characteristics of lift-off velocity with analytically derived vector expression. Compared with a single asteroid system, there is an external perturbed body that has influence on the dynamic environment of the… read more here.

DOI: 10.1016/j.icarus.2021.114826
Abstract: Using viscoelastic mass/spring model simulations, we explore tidal evolution and migration of compact binary asteroid systems. We find that after the secondary is captured into a spin-synchronous state, non-principal axis rotation in the secondary can… read more here.

DOI: 10.1093/mnras/staa1229
Abstract: The orbital dynamics in the vicinity of a binary asteroid system has been studied extensively, motivated by the special dynamical environment and possible exploration missions. Equilibrium points, periodic orbits, and invariant manifolds have been investigated… read more here.
