Spatial resonant periodic orbits in the restricted three-body problem
K. I. Antoniadou, A. -S. Libert
The quest of exo-Earths has become a prominent field. In this work, we study the stability of non-coplanar planetary configurations consisting of an inclined inner terrestrial plan…
On quasi-satellite periodic motion in asteroid and planetary dynamics
G. Voyatzis, K. I. Antoniadou
Applying the method of analytical continuation of periodic orbits, we study quasi-satellite motion in the framework of the three-body problem. In the simplest, yet not trivial mode…
Origin and continuation of 3/2, 5/2, 3/1, 4/1 and 5/1 resonant periodic orbits in the circular and elliptic restricted three-body problem
Kyriaki I. Antoniadou, Anne-Sophie Libert
We consider a planetary system consisting of two primaries, namely a star and a giant planet, and a massless secondary, say a terrestrial planet or an asteroid, which moves under t…
Puzzling out the coexistence of terrestrial planets and giant exoplanets. The 2/1 resonant periodic orbits
Kyriaki I. Antoniadou, Anne-Sophie Libert
Hundreds of giant planets have been discovered so far and the quest of exo-Earths in giant planet systems has become intriguing. In this work, we aim to address the question of the…
Influence of periodic orbits on the formation of giant planetary systems
Anne-Sophie Libert, Sotiris Sotiriadis, Kyriaki I. Antoniadou
The late-stage formation of giant planetary systems is rich in interesting dynamical mechanisms. Previous simulations of three giant planets initially on quasi-circular and quasi-c…
Inclined asymmetric librations in exterior resonances
G. Voyatzis, K. Tsiganis, K. I. Antoniadou
Librational motion in celestial mechanics is generally associated with the existence of stable resonant configurations and signified by the existence of stable periodic solutions a…
