Particles co-orbital to Janus and Epimetheus: a firefly planetary ring
Othon C. Winter, Alexandre P. S. Souza, Rafael Sfair +3
The Cassini spacecraft found a new and unique ring that shares the trajectory of Janus and Epimetheus, co-orbital satellites of Saturn. Performing image analysis, we found this to…
Poincaré surfaces of section around a 3-D irregular body: The case of asteroid 4179 Toutatis
Gabriel Borderes Motta, Othon Cabo Winter
In general, small bodies of the solar system, e.g., asteroids and comets, have a very irregular shape. This feature affects significantly the gravitational potential around these i…
The rings of Chariklo under close encounters with the giant planets
R. A. N. Araujo, R. Sfair, O. C. Winter
The Centaur population is composed by minor bodies wandering between the giant planets and that frequently perform close gravitational encounters with these planets, which leads to…
Stable retrograde orbits around the triple system 2001 SN263
R. A. N. Araujo, O. C. Winter, A. F. B. A. Prado
The NEA 2001 SN263 is the target of the ASTER MISSION - First Brazilian Deep Space Mission. Araujo et al. (2012), characterized the stable regions around the components of the trip…
On the Stability of the Satellites of Asteroid 87 Sylvia
O. C. Winter, L. A. G. Boldrin, E. Vieira Neto +5
he triple asteroidal system (87) Sylvia is composed of a 280-km primary and two small moonlets named Romulus and Remus (Marchis et al 2005). Sylvia is located in the main asteroid…
A Possible Stellar Metallic Enhancement in Post-T Tauri Stars by a Planetesimal Bombardment
O. C. Winter, R. de la Reza, R. C. Domingos +2
The photospheres of stars hosting planets have larger metallicity than stars lacking planets. In the present work we study the possibility of an earlier metal enrichment of the pho…
