On the dynamics of the three dimensional planetary systems
Kyriaki I. Antoniadou, George Voyatzis, John D. Hadjidemetriou
Over the last decades, there has been a tremendous increase in research on extrasolar planets. Many exosolar systems, which consist of a Star and two inclined Planets, seem to be l…
Resonant periodic orbits in the exoplanetary systems
K. I. Antoniadou, G. Voyatzis
The planetary dynamics of , , , and mean motion resonances is studied by using the model of the general three body problem in a rotating frame and by det…
Dynamics of Three Non-co-rotating Vortices in Bose-Einstein Condensates
Vassilis Koukouloyannis, George Voyatzis, Panayotis G. Kevrekidis
In this work we use standard Hamiltonian-system techniques in order to study the dynamics of three vortices with alternating charges in a confined Bose-Einstein condensate. In addi…
Resonant planetary dynamics: Periodic orbits and long-term stability
George Voyatzis, Kyriaki I. Antoniadou, John D. Hadjidemetriou
Many exo-solar systems discovered in the last decade consist of planets orbiting in resonant configurations and consequently, their evolution should show long-term stability. Howev…
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…
