• Abstract

  In orbital dynamics, minor bodies are those that have size (and mass) much smaller than at least one of the other bodies (called primaries) of the system that belong to. One case very common in astronautics is the case of a spacecraft traveling within the sun-earth-moon system. This kind of characteristic makes the dynamics of the system to present some peculiarities. One of them is the f…

• Abstract

  Planetary arcs, the densest parts of a planetary ring, can be found in the planetary systems of Saturn and Neptune. In Neptune, these arcs (Fraternité, Egalité, Courage and Egalité) are located in the tenuous Adams ring. To constrain the spreading of the arcs, due to keplerian shear and dissipative forces, a recent confinement mechanism proposed that the azimuthal confinement is due to co…

  Scenarios for the formation of Neptune's arcs and the giant satellites of the Solar System, BP.DR

• Abstract

  The first planetary arcs were discovered in the 1980s on the Adams ring of Neptune. Similar structures has been discover on Saturn. The stability of these systems is usually attributed to resonances, as occurs with the arcs of Anthe, Methone and the G ring. These arcs is on Saturn and the searchers believes they are maintained by corotation resonances with Mimas. The stability of the Adam…

  Orbital evolution study of particles in Lindblad and corotation resonances and under influence of coorbitals satellites: planetary arcs application, BP.MS

• Abstract

  A new class of system was discovered in the Saturn system, a close relation between small satellites and ring particles. The small satellites, Anthe, Methone, Pallene and Aegaoen are immersed in arcs or complete rings, mainly composed by tiny particles. In this project the orbital evolution of the small satellites, since they are in mean motion resonance with the satellite Mimas, under th…

• Abstract

  JAXA's Martian Moon eXploration (MMX) mission is expected to arrive on the Mars system in 2023 for a complete observational and geological study of the martian system. The mission, which will also collect samples of the moon Phobos, aims to answer the main question: How did the martian moons, Phobos and Deimos, form? Formation models propose the formation of these moons in a debris disk g…
