Dynamics of the Edgeworth-Kuiper Belt beyond 50 AU : Spread of a primordial thin disk

In this paper we report numerical simulations of the dynamical evolution of the region a > 50 AU. We found that some dynamical effects such as high-order secular resonances with the rate of precession of Neptune's node of the form kΩ· − Ω·<sub>Nep</sub> with k = 4,5, ... or combi...

Descrição
Resumo:In this paper we report numerical simulations of the dynamical evolution of the region a > 50 AU. We found that some dynamical effects such as high-order secular resonances with the rate of precession of Neptune's node of the form kΩ· − Ω·<sub>Nep</sub> with k = 4,5, ... or combined mean motion resonances with Uranus and Neptune of the form kn<sub>N</sub> + jn<sub>U</sub> + mn ∼ 0 may increase the area of a very thin primordial disk in this region by a factor of up to 2 after 4.5 Gy of evolution.
