The Spin–Spin Problem in Celestial Mechanics [PDF]

open access: yesJournal of Nonlinear Science, 2021
We study the dynamics of two homogeneous rigid ellipsoids subject to their mutual gravitational influence. We assume that the spin axis of each ellipsoid coincides with its shortest physical axis and is perpendicular to the orbital plane.

Old perturbative methods for a new problem in Celestial Mechanics: the space debris dynamics [PDF]

open access: hybridBollettino dell'Unione Matematica Italiana, 2023
Perturbative methods have been developed and widely used in the XVIII and XIX century to study the behavior of N -body problems in Celestial Mechanics. Such methods apply to nearly-integrable Hamiltonian systems and they have the remarkable property to ...

Degenerate billiards in celestial mechanics [PDF]

open access: yesRegular and Chaotic Dynamics, 2016
In an ordinary billiard trajectories of a Hamiltonian system are elastically reflected after a collision with a hypersurface (scatterer). If the scatterer is a submanifold of codimension more than one, we say that the billiard is degenerate.

celmech: A Python Package for Celestial Mechanics [PDF]

open access: yesAstronomical Journal, 2022
We present celmech, an open-source Python package designed to facilitate a wide variety of celestial mechanics calculations. The package allows users to formulate and integrate equations of motion incorporating user-specified terms from the classical ...

Numerical integration in Celestial Mechanics: a case for contact geometry [PDF]

open access: yesCelestial mechanics & dynamical astronomy, 2020
Several dynamical systems of interest in Celestial Mechanics can be written in the form of a Newton equation with time-dependent damping, linear in the velocities.

Universal symbolic expression for radial distance of conic motion [PDF]

open access: yesSerbian Astronomical Journal, 2014
In the present paper, a universal symbolic expression for radial distance of conic motion in recursive power series form is developed. The importance of this analytical power series representation is that it is invariant under many operations ...
