Forming Mercury by a grazing giant collision involving similar mass bodies

Autor: Patrick de Oliveira, Fernando Roig, Othon Winter, Rafael Sfair, Christoph Burger, Christoph Schäfer

The planet Mercury is predominantly made up of an iron core, covered by a comparatively thin silicate layer, which has led to the idea that this configuration is the product of mantle stripping by a giant impact. In the literature, a classical hit-an

Study of the Sailboat stable region for binary systens

Autor: Tiago Pinheiro, Rafael Sfair, Ernesto Vieira

The sailboat region was first identified by Giuliatti Winter, et al. (2010) exploring the Pluto-Charon binary system, they identifed this unexpected stable region of S-type orbits around the dwarfplanet Pluto located at a = (0.5d, 0.7d) and e = (0.2,

Transneptunian Objects (TNOs) are the remnants of our planetary system and can retain information about the early stages of the Solar System formation. Stellar occultation is a ground-based method used to study these distant bodies which have been pr
