Families of Halo-like invariant tori around \(L_2\) in the Earth-Moon bicircular problem
In this paper the dynamics of a particle in the Earth-Moon Restricted Three-Body Problem (RTBP), that includes the direct gravitational effect of the Sun, is studied. The paper focuses on the dynamics around the L2 point in the Bicircular Problem (BCP), which is a periodic time dependent perturbation of the Earth-Moon (RTBP) that includes the direct gravitational effect of the Sun, in order to study the existence of Halo-like orbits. The authors compute families of 2D invariant tori, and they show that there are at least two different families of Halo-like quasi-periodic orbits around L2. The focus in Halo-like orbits are not arbitrary, and it responds to the application that these trajectories have for lunar missions. The authors mention that all the tools and techniques, in the paper, are model-agnostic.
