Cylindrical Manifolds and Tube Dynamics in the Restricted Three-Body Problem [PDF]

open access: yes, 2004
Within the phase space of the planar circular restricted three-body problem, stable and unstable manifolds of periodic orbits with a S x R (cylindrical) geometry are shown to exist.

Low thrust propulsion in a coplanar circular restricted four body problem [PDF]

open access: yes, 2012
This paper formulates a circular restricted four body problem (CRFBP), where the three primaries are set in the stable Lagrangian equilateral triangle configuration and the fourth body is massless.

A topological approach for segmenting human body shape [PDF]

open access: yes, 2003
Segmentation of a 3D human body, is a very challenging problem in applications exploiting human scan data. To tackle this problem, the paper proposes a topological approach based on the discrete Reeb graph (DRG) which is an extension of the classical ...

A Numerical Contribution to the Hierarchical Three-Body Problem [PDF]

open access: yes, 2022
The aim of this thesis is to provide a numerical investigation of the motions of the planar hierarchical three body problem, that we will regard as a perturbation of the planar two centre problem.

On an Application of the Hill Approach to the General Case of the Three-body Problem

open access: yesThe Astronomical Journal
In this work, we use the energy and angular momentum integrals as a resource for applying Hill’s approach to the general three-body problem. As a result, we obtain theorems on the Lagrange stability and Hill stability in the general three-body problem ...

Numerical Determination of the Gravitational Cross Sections of an Accreting Binary

open access: yesThe Astrophysical Journal
A significant amount of work has been devoted to the study of small binary solar system objects. The majority of these binaries, especially among the near-Earth or main belt asteroids, have small radius ratios, implying a large difference in size between
