Post-Newtonian orbital mechanics around a black hole in modified gravity
Ioannis Liodis, Gernot Heissel, Rita Mastroioanni +2
Scalar-tensor-vector gravity, also known as modified gravity (MOG), has emerged as an alternative to General Relativity (GR). It aims to explain astrophysical phenomena without inv…
Fully analytical propagator for lunar satellite orbits in closed form
Rita Mastroianni, Edoardo Legnaro, Christos Efthymiopoulos
We present a fully analytical propagator for the orbits of lunar artificial satellites in a lunar gravity and third-body model sufficiently precise for a wide range of practical ap…
Bifurcation sequences in the secular 3D planetary 3-Body problem: a geometric approach
Rita Mastroianni, Antonella Marchesiello, Christos Efthymiopoulos +1
We implement the geometric method proposed in ([9], [3], [16]) to analytically predict the sequence of bifurcations leading to a change of stability and/or the appearance of new pe…
Computer-assisted proofs of existence of KAM tori in planetary dynamical models of -And
Rita Mastroianni, Ugo Locatelli
We reconsider the problem of the orbital dynamics of the innermost exoplanet of the -Andromedae system (i.e., -And ) into the framework of a Secular…
Secular orbital dynamics of the innermost exoplanet of the -Andromedæ system
Rita Mastroianni, Ugo Locatelli
We introduce a quasi-periodic restricted Hamiltonian to describe the secular motion of a small-mass planet in a multi-planetary system. In particular, we refer to the motion of $\u…
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…
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…
