Generalizations of the Störmer Problem for Dust Grain Orbits
نویسنده
چکیده
We consider the generalized Störmer Problem that includes the electromagnetic and gravitational forces on a charged dust grain near a planet. For dust grains a typical charge to mass ratio is such that neither force can be neglected. Including the gravitational force gives rise to stable circular orbits that encircle that plane entirely above/below the equatorial plane. The effects of the different forces are discussed in detail. A modified 3rd Kepler’s law is found and analyzed for dust grains. PACS: 96.30.Wr, 45.50.Jf, 96.35.Kx

The Temperature and Mass Effects on Dust Grain Electrical Potential in Dusty Plasma
By orbit-limited motion (OLM) theory and the kinetic model, currents carried by electronsand ions on the dust grain are obtained and the effects of temperature and drift velocity of ions on thedust grain electrical potential are considered. The calculations were performed for finding the role of densities of dust grains and ions on the dust grain electrical potential which is the ma...
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 کاملA Mathematical Optimization Model for Solving Minimum Ordering Problem with Constraint Analysis and some Generalizations
In this paper, a mathematical method is proposed to formulate a generalized ordering problem. This model is formed as a linear optimization model in which some variables are binary. The constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. On the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...

A new guidance scheme for the problem of Low-thrust transfer between inclined orbits is developed within the framework of optimal control theory. The objective of the guidance scheme is to provide the appropriate thrust steering program that will transfer the vehicle from an inclined low earth orbits to the high earth orbits. The presented guidance scheme is determined using Pontryagin’s princi...
متن کاملDust-driven Dynamos in Accretion Disks
Magnetically driven astrophysical jets are related to accretion and involve toroidal magnetic field pressure inflating poloidal magnetic field flux surfaces. Examination of particle motion in combined gravitational and magnetic fields shows that these astrophysical jet toroidal and poloidal magnetic fields can be powered by the gravitational energy liberated by accreting dust grains that have b...
