Stability and bifurcations of the figure-8 solution of the Three-boday problem
J. Galan, F.J. Munoz-Almaraz, and E. Freire, E. Doedel, and A. Vanderbauwhede
Phys. Rev. Lett. 88, 241101 (2002)
abstract\$B\$O!\$ The stability properties of a recently discovered solution of the general three-body problem with equal masses and the shape of a figure 8 are analyzed as the masses are varied. It is shown by numerical continuation and the evaluation of the characteristic multipliers that the solution is stable only in a narrow mass interval. Other less symmetrical and unstable solutions with equal masses in the same homotopy class as the figure-8 orbit have been found. The branching behavior is also analyzed.
