Semi-analytical estimates for the chaotic diffusion in the Second Fundamental Model of Resonance. Application to Earth's navigation satellites
Edoardo Legnaro, Christos Efthymiopoulos, Maria Harsoula
We discuss the applicability of the Melnikov and Landau-Teller theories in obtaining semi-analytical estimates of the speed of chaotic diffusion in systems driven by the separatrix…
Relegation-free closed-form perturbation theory and the domain of secular motions in the Restricted 3-Body Problem
Mattia Rossi, Christos Efthymiopoulos
We propose a closed-form (i.e. without expansion in the orbital eccentricities) scheme for computations in perturbation theory in the restricted three-body problem (R3BP) when the…
Action-Angle formalism for extreme mass ratio inspirals in Kerr spacetime
Morteza Kerachian, Lukáš Polcar, Viktor Skoupý +2
We introduce an action-angle formalism for bounded geodesic motion in Kerr black hole spacetime using canonical perturbation theory. Namely, we employ a Lie series technique to pro…
The phase-space architecture in extrasolar systems with two planets in orbits of high mutual inclination
Rita Mastroianni, Christos Efthymiopoulos
We revisit the secular 3D planetary three-body problem aiming to provide a unified formalism for studying the structure of the phase space for progressively higher values of the mu…
A detailed dynamical model for inclination-only dependent lunisolar resonances. Effect on the "eccentricity growth" mechanism
Edoardo Legnaro, Christos Efthymiopoulos
The focus of this paper is on inclination-only dependent lunisolar resonances, which shape the dynamics of a MEO (Medium Earth Orbit) object over secular time scales (i.e. several…
Kolmogorov algorithm for isochronous Hamiltonian systems
Rita Mastroianni, Christos Efthymiopoulos
We present a Kolmogorov-like algorithm for the computation of a normal form in the neighborhood of an invariant torus in `isochronous' Hamiltonian systems, i.e., systems with Hamil…
