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…
An Exoplanet's Response to Anisotropic Stellar Mass-Loss During Birth and Death
Dimitri Veras, John D. Hadjidemetriou, Christopher A. Tout
The birth and death of planets may be affected by mass outflows from their parent stars during the T-Tauri or post-main-sequence phases of stellar evolution. These outflows are oft…
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…
The 1:1 resonance in Extrasolar Systems: Migration from planetary to satellite orbits
John D. Hadjidemetriou, George Voyatzis
We present families of symmetric and asymmetric periodic orbits at the 1/1 resonance, for a planetary system consisting of a star and two small bodies, in comparison to the star, m…
On the dynamics of Extrasolar Planetary Systems under dissipation. Migration of planets
J. D. Hadjidemetriou, G. Voyatzis
We study the dynamics of planetary systems with two planets moving in the same plane, when frictional forces act on the two planets, in addition to the gravitational forces. The mo…
