Spatial Relative Equilibria and Periodic Solutions of the Coulomb $$(n+1)$$-Body Problem

Quasi-periodic Solutions of the Spatial Lunar Three-body Problem

In this paper, we consider the spatial lunar three-body problem in which one body is far-away from the other two. By applying a well-adapted version of KAM theorem to Lidov-Ziglin’s global study of the quadrupolar approximation of the spatial lunar three-body problem, we establish the existence of several families of quasi-periodic orbits in the spatial lunar three-body problem.

Normal Form Theory for Relative Equilibria and Relative Periodic Solutions

We show that in the neighbourhood of relative equilibria and relative periodic solutions, coordinates can be chosen so that the equations of motion, in normal form, admit certain additional equivariance conditions up to arbitrarily high order. In particular, normal forms for relative periodic solutions effectively reduce to normal forms for relative equilibria, enabling the calculation of the d...

Finiteness of Relative Equilibria of the Four-body Problem

We show that the number of relative equilibria of the Newtonian four-body problem is finite, up to symmetry. In fact, we show that this number is always between 32 and 8472. The proof is based on symbolic and exact integer computations which are carried out by computer.

Bifurcation of Relative Equilibria of the (1+3)-Body Problem

We study the relative equilibria of the limit case of the planar Newtonian 4–body problem when three masses tend to zero, the so-called (1 + 3)–body problem. Depending on the values of the infinitesimal masses the number of relative equilibria varies from ten to fourteen. Always six of these relative equilibria are convex and the others are concave. Each convex relative equilibrium of the (1 + ...
