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…
