The NHIM bifurcation scenario of a particle in an asymmetric binary system of dwarf galaxies
Christof Jung, Francisco Gonzalez Montoya
We study the bifurcation scenario of a three-degree-of-freedom Hamiltonian system, a model based on the Lagrange restricted 3-body problem: a test particle moving in the gravitatio…

Indicator Functions Detect Tangentially Transient Behaviour on Decaying Normally Hyperbolic Invariant Manifolds
Francisco Gonzalez Montoya, Christof Jung
We study the decay scenario of a codimension-2 NHIM in a three degrees of freedom Hamiltonian system under increasing perturbation when the NHIM loses its normal hyperbolicity. On…

Impenetrable Barriers in the Phase Space of a Particle Moving Around a Kerr Rotating Black Hole
Francisco Gonzalez Montoya
We study the phase space of a particle moving in the gravitational field of a rotating black hole described by the Kerr metric from a geometrical perspective. In particular, we sho…
