3D analytical theory of the perturbed single-synchronous state. Application to the post-impact Didymos-Dimorphos system
Michalis Gaitanas, Christos Efthymiopoulos, Ioannis Gkolias +2
We develop the 3D generalization of the planar analytical theory presented in Gaitanas et. al., 2024, which deals with states slightly perturbed from the exact `single-synchronous…
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…
Analytical theory of the spin-orbit state of a binary asteroid deflected by a kinetic impactor
Michalis Gaitanas, Christos Efthymiopoulos, Ioannis Gkolias +2
We study the perturbed-from-synchronous librational state of a double asteroid, modeled by the Full Two Rigid Body Problem (F2RBP), with primary emphasis on deriving analytical for…
Secular dynamics and the lifetimes of lunar artificial satellites under natural force-driven orbital evolution
Edoardo Legnaro, Christos Efthymiopoulos
In this paper, we study the long-term (time scale of several years) orbital evolution of lunar satellites under the sole action of natural forces. In particular, we focus on secula…
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…
SELENA: Semi-analytical Integrator for Lunar Artificial Satellites
Christos Efthymiopoulos, Kleomenis Tsiganis, Ioannis Gkolias +2
The present report summarizes the main theory and implementation steps associated with SELENA (SEmi-anaLytical intEgrator for a luNar Artificial satellite), i.e. the semi-analytica…
