Stability of halo orbits.

چکیده
We predict new populations of trapped nonequatorial ("halo") orbits of charged dust grains about an arbitrary axisymmetric planet. Simple equilibrium and stability conditions are derived, revealing dramatic differences between positively and negatively charged grains in prograde or retrograde orbits. Implications for the Cassini mission to Saturn are discussed.

Aas 08-200 Subregions of Motion and Elliptic Halo Orbits in the Elliptic Restricted Three-body Problem
In this paper we present regions of motion and periodic orbits in the spatial elliptic restricted three body problem (ER3BP). Periodic orbits and regions of motion are fundamental keys to understand any dynamical system; for this reason the Hill’s surfaces or the families of halo orbits have been extensively studied in the frame of the circular restricted three body problem. It is our opinion t...
متن کاملFuzzy Sliding Mode for Spacecraft Formation Control in Eccentric Orbits
The problem of relative motion control for spacecraft formation flying in eccentric orbits is considered in this paper. Due to the presence of nonlinear dynamics and external disturbances, a robust fuzzy sliding mode controller is developed. The slopes of sliding surfaces of the conventional sliding mode controller are tuned according to error states using a fuzzy logic and reach the pre-define...
متن کاملProbing the shape and history of the Milky Way halo with orbital spectral analysis
Accurate phase-space coordinates (three components of position and velocity) of individual stars are rapidly becoming available with current and future resolved star surveys. These data will enable the computation of the full three-dimensional orbits of tens of thousands of stars in the Milky Way’s stellar halo. We demonstrate that the analysis of stellar halo orbits in frequency space can be u...
متن کاملDark Halo Orbits and Tidal Stripping with the Spirographic Approximation
This paper discusses the orbit of a small dark matter halo, mass = .1M inside of a larger halo, mass = M. Using the spirographic approximation for the orbits, it addresses the effect of three orbital parameters: energy, angular momentum, and a frictional coefficient. Next, it analyzes the way mass is stripped from the small halo through tidal forces and the effect of the ratio of the density sc...
متن کاملDensity waves in the shearing sheet IV . Interaction with a live dark halo B
It is shown that if the self–gravitating shearing sheet, a model of a patch of a galactic disk, is embedded in a live dark halo, this has a strong effect on the dynamics of density waves in the sheet. I describe how the density waves and the halo interact via halo particles either on orbits in resonance with the wave or on non-resonant orbits. Contrary to expectation the presence of the halo le...
