Irregular satellites of Jupiter: capture configurations of binary-asteroids
TL;DR: In this paper, the authors performed more than eight thousand numerical simulations of capture trajectories considering the four-body dynamical system Sun, Jupiter, Binary Asteroid, and restricted the problem to the circular planar prograde case, and time of integration to 10 4 years.
Journal ArticleDOI

TL;DR: In this paper, the authors focused on processing the complete photometric observations data base to compute new accurate astrometric positions from the light curves of the mutual occultations and eclipses.
Journal ArticleDOI
Analysis of 25 mutual eclipses and occultations between the Galilean satellites observed from Brazil in 2009
A. Dias-Oliveira,R. Vieira-Martins,Marcelo Assafin,Julio Camargo,Felipe Braga-Ribas,D. N. da Silva Neto,H. S. Gaspar,P. M. Pires dos Santos,R. C. Domingos,L. A. G. Boldrin,Andre Izidoro,J. P. S. Carvalho,Rafael Sfair,Jarbas Cordeiro Sampaio,Othon C. Winter +14 more
TL;DR: In this article, the authors used the Oren-Nayar reflexive model to map the inhomogeneous light scattering on the surface of the satellites of the Earth and fitted the occultation and eclipse light curves using semi-analytical models that take into account the gradual decrease of light over the shadow, the solar limb darkening and the solar phase angle.
Journal ArticleDOI
Irregular satellites of Jupiter: three-dimensional study of binary-asteroid captures
TL;DR: In this paper, Pereira da Cunha et al. presented a study on the feasibility of using satellite technology in the field of Dinamica Orbital and Planetologia (GODP).
Journal ArticleDOI
