Several space-based climate engineering methods, including shading the Earth with a particle ring for active cooling, or the use of orbital reflectors to increase the total insolation of Mars for climate warming have been ...

In this work the problem of a spacecraft bi-impulsive transfer between two given non coplanar elliptical orbits, with minimum fuel consumption, is solved considering a non-Keplerian force field (the perturbing forces include ...

The present work using analytic and geometric methods to study differential equations and systems of differential equations. Although some of the tools developed here are intended to be applied to arbitrary equation, the ...

The purpose of this paper is to make a numerical search for natural orbits that can be used for a spacecraft to study a possible small moon of Pallas. There are many speculations about the existence of a small companion ...

Context. More than 40 planets have been found around giant stars, revealing a lack of systems orbiting interior to ∼0.6 AU. This observational fact contrasts with the planetary population around solar-type stars and has ...

Recent observations of stellar occultations have revealed rings of particles around non-planetary bodies of the Solar system. These bodies are irregular and can be modelled by ellipsoids. In the context of numerical ...

The present work presents a test of two Hamiltonians that produce integrable models recently proposed to study the roto-orbital motion of an axisymmetric rigid body in motion under a central gravitational field. The dynamics ...
