Experiments in orbit determination using numerical methods [PDF]
, 1985 The dynamics of the observed object is written as a system of integral equations. This system is solved numerically by representing the components of the force function as linear combinations of B-splines and by applying the multigrid technique.

Dynamics of charged dust in the orbit of Venus [PDF]
Astronomy & Astrophysics, 2021 We study the dynamics of co-orbital dust in the inner Solar System, that is, the role of the solar radiation pressure, the Poynting-Robertson effect, the solar wind, and the interplanetary magnetic field, on the location, width, and stability of resonant motion of charged and micron-sized dust grains situated in the 1:1 mean motion resonance with Venus.

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub
International Journal of Rotating Machinery, 2000 The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...

The Orbits and Dynamical Masses of the Castor System
The Astrophysical Journal, 2022 Abstract Castor is a system of six stars in which the two brighter objects, Castor A and B, revolve around each other every ∼450 yr and are both short-period spectroscopic binaries. They are attended by the more distant Castor C, which is also a binary.

Orbit Decomposition Method for Rotordynamic Coefficients Identification of Annular Seals
Applied Sciences, 2021 The elliptical orbit whirl model is widely used to identify the frequency-dependent rotordynamic coefficients of annular seals. The existing solution technique of an elliptical orbit whirl model is the transient computational fluid dynamics (CFD) method.

Dynamics of interacting fermions under spin–orbit coupling in an optical lattice clock [PDF]
, 2017 Quantum statistics and symmetrization dictate that identical fermions do not interact via s-wave collisions. However, in the presence of spin–orbit coupling (SOC), fermions prepared in identical internal states with distinct momenta become ...

Axial to transverse energy mixing dynamics in octupole-based magnetostatic antihydrogen traps
New Journal of Physics, 2018 The nature of the trajectories of antihydrogen atoms confined in an octupole minimum-B trap is of great importance for upcoming spectroscopy, cooling, and gravity experiments.

Dynamical Friction and Orbit Circularization [PDF]
Symposium - International Astronomical Union, 1987 We study the change in shape of the orbit of a satellite sinking (because of dynamical friction) towards the center of a larger galaxy. the galaxy is assumed spherically symmetric with distribution function either isotropic or predominantly radial. the satellite is a softened point mass.

Simulation of Spin-orbit Dynamics in Storage Rings
, 2016 In the article a mapping approach based on nonlinear matrix integration for longterm spin-orbit dynamics simulation is briefly described. Using this technique the nonlinear effects of spin dynamics in an electrostatics storage ring are investigated ...
