Strategies for plane change of Earth orbits using lunar gravity and derived trajectories of family G
(Springer, 2009-04-01)
The dynamics of the circular restricted three-body Earth-Moon-particle problem predicts the existence of the retrograde periodic orbits around the Lagrangian equilibrium point L1. Such orbits belong to the so-called family ...
Studying Close Approaches for a Cloud of Particles Considering Atmospheric Drag
(Hindawi Publishing Corporation, 2013-01-01)
The present paper has the goal of studying close approaches between a planet and a group of particles. The mathematical model includes the presence of the atmosphere of the planet. This cloud is assumed to be created by ...
Dynamics of Space Particles and Spacecrafts Passing by the Atmosphere of the Earth
(Hindawi Publishing Corporation, 2013-01-01)
The present research studies the motion of a particle or a spacecraft that comes from an orbit around the Sun, which can be elliptic or hyperbolic, and that makes a passage close enough to the Earth such that it crosses ...
Exploring S-type orbits in the Pluto-Charon binary system
(Wiley-Blackwell, 2010-05-01)
This work generates, through a sample of numerical simulations of the restricted three-body problem, diagrams of semimajor axis and eccentricity which defines stable and unstable zones for particles in S-type orbits around ...

Searching for orbits around the triple asteroid 2001SN263
(2017-10-25)
The asteroid 2001SN263 is one of the possible targets of a proposed mission that would be the first Brazilian exploration in deep space, the Aster Mission. This asteroid is composed by three bodies: Alpha, Beta, and Gamma, ...
Two-degree-of-freedom vortex-induced vibration of circular cylinders with very low aspect ratio and small mass ratio
(London, 2014-02-05)
The investigation of vortex-induced vibration on very short cylinders with two degrees of freedom has drawn the attention of a large number of researchers. Some investigations on such a problem are carried out in order to ...
