1/1 resonant periodic orbits in three dimensional planetary systems

Kyriaki I. Antoniadou, George Voyatzis, Harry Varvoglis

We study the dynamics of a two-planet system, which evolves being in a mean motion resonance (co-orbital motion) with non-zero mutual inclination. In particular, we examine t…

Continuation and stability deduction of resonant periodic orbits in three dimensional systems

Kyriaki I. Antoniadou, George Voyatzis, Harry Varvoglis

In dynamical systems of few degrees of freedom, periodic solutions consist the backbone of the phase space and the determination and computation of their stability is crucial for u…

Multi-Planet Destabilisation and Escape in Post-Main Sequence Systems

George Voyatzis, John D. Hadjidemetriou, Dimitri Veras +1

Discoveries of exoplanets orbiting evolved stars motivate critical examinations of the dynamics of -body systems with mass loss. Multi-planet evolved systems are particularly co…

Interaction of free-floating planets with a star-planet pair

Harry Varvoglis, Vasiliki Sgardeli, Kleomenis Tsiganis

The recent discovery of free-floating planets and their theoretical interpretation as celestial bodies, either condensed independently or ejected from parent stars in tight cluster…

The dynamics of the elliptic Hill problem : Periodic orbits and stability regions

G. Voyatzis, I. Gkolias, H. Varvoglis

The motion of a satellite around a planet can be studied by the Hill model, which is a modification of the restricted three body problem pertaining to motion of a satellite around…

The power spectrum of geodesic divergences as an early detector of chaotic motion

Ch. L. Vozikis, H. Varvoglis, K. Tsiganis

We propose a new method for determining the stochastic or ordered nature of trajectories in non-integrable Hamiltonian dynamical systems. The method consists of constructing a time…

Imperfect fractal repellers and irregular families of periodic orbits in a 3-D model potential

B. Barbanis, H. Varvoglis, Ch. L. Vozikis

A model, plane symmetric, 3-D potential, which preserves some features of galactic problems,is used in order to examine the phase space structure through the study of the propertie…

Higher-dimensional models in gravitational theories of quarticLagrangians

K. Kleidis, A. Kouirukidis, D. B. Papadopoulos +1

Ten-dimensional models, arising from a gravitational action which includes terms up to the fourth order in curvature tensor, are discussed. The spacetime consists of one timelike d…
