Measuring the transition between nonhyperbolic and hyperbolic regimes in open Hamiltonian systems
Alexandre R. Nieto, Euaggelos E. Zotos, Jesús M. Seoane +1
We show that the presence of KAM islands in nonhyperbolic chaotic scattering has deep implications on the unpredictability of open Hamiltonian systems. When the energy of the syste…
Numerical investigation on the Hill's type lunar problem with homogeneous potential
Yanxia Deng, Slim Ibrahim, Euaggelos E. Zotos
We consider the planar Hill's lunar problem with a homogeneous gravitational potential. The investigation of the system is twofold. First, the starting conditions of the trajectori…
Escaping from a degenerate version of the four hill potential
Euaggelos E. Zotos, Wei Chen, Christof Jung
We examine the escape from the four hill potential by using the method of grid classification, when polar coordinates are used for expressing the initial conditions of the orbits.…
Orbital and escape dynamics in barred galaxies -- IV. Heteroclinic connections
Euaggelos E. Zotos, Christof Jung
Continuing the series of papers on a new model for a barred galaxy, we investigate the heteroclinic connections between the two normally hyperbolic invariant manifolds sitting over…
Orbit classification in a pseudo-Newtonian Copenhagen problem with Schwarzschild-like primaries
Euaggelos E. Zotos, Fredy L. Dubeibe, Jan Nagler +1
We examine the orbital dynamics of the planar pseudo-Newtonian Copenhagen problem, in the case of a binary system of Schwarzschild-like primaries, such as super-massive black holes…
On the fractal basins of convergence of the libration points in the axisymmetric five-body problem: the convex configuration
Md Sanam Suraj, Prachi Sachan, Euaggelos E. Zotos +2
In the present work, the Newton-Raphson basins of convergence, corresponding to the coplanar libration points (which act as numerical attractors), are unveiled in the axisymmetric…
