Lyapunov and Halo Orbits about L
We develop and illustrate techniques to obtain periodic orbits around the second Lagrangian point L2 in the Sun-Earth system based on the Restricted Three-Body Problem. In the case of Lyapunov (planar) orbits, the solutions to the linearized equations of motion allow the generation of the entire family of orbits. For Halo orbits, however, the method of strained coordinates is applied to generat...
متن کاملSun-earth L1 Region Halo-to-halo Orbit and Halo-to-lissajous Orbit Transfers
Practical techniques for designing transfer trajectories between Libration Point Orbits (LPOs) are presented. Motivation for development of these techniques was provided by a hardware contingency experienced by the Solar Heliospheric Observatory (SOHO), a joint mission of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) orbiting the L1 point of the Su...
متن کاملLow-Velocity Halo Clouds
Models that reproduce the observed high-velocity clouds (HVCs) also predict clouds at lower radial velocities that may easily be confused with Galactic disk (|z| < 1 kpc) gas. We describe the first search for these low-velocity halo clouds (LVHCs) using IRAS data and the initial data from the Galactic Arecibo L-band Feed Array survey in Hi (GALFA-Hi). The technique is based upon the expectation...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
