Orbital Uncertainty Propagation Based on Adaptive Gaussian Mixture Model under Generalized Equinoctial Orbital Elements

open access: yesRemote Sensing, 2023
The number of resident space objects (RSOs) has been steadily increasing over time, posing significant risks to the safe operation of on-orbit assets. The accurate prediction of potential collision events and implementation of effective and nonredundant ...

Orbital phase in inspiralling compact binaries [PDF]

open access: yes, 2007
We derive the rate of change of the mean motion up to the second post-Newtonian order for inspiralling compact binaries with spin, mass quadrupole and magnetic dipole moments on eccentric orbits. We give this result in terms of orbital elements.

Impulsive Maneuvers for Formation Reconfiguration Using Relative Orbital Elements

open access: yes, 2015
Advanced multisatellite missions based on formation-flying and on-orbit servicing concepts require the capability to arbitrarily reconfigure the relative motion in an autonomous, fuel efficient, and flexible manner.

Statistical distributions of Centaurs' orbital elements

open access: yesВісник Астрономічної школи, 2011
In this paper the Centaurs' orbital elements distribution is considered. Centaurs under consideration are 82 currently known objects with perihelia in the domain of giant planets and aphelia below 50 AU.

New orbital elements of 5 interferometric double stars [PDF]

open access: yesSerbian Astronomical Journal, 1999
In this paper, for the first time, are presented elliptical and Thiel- Innes orbitatal elements for the following interferometric pairs: WDS 00416+2438 = WRH, WDS 03271+1845 = CHARA 10, WDS 04044+2406 = McA 13 Aa, WDS 17095+4047 = McA 45 and WDS

Mean Orbital Elements of a Near-Circular Orbiting Artificial Satellite due to the Earth's Zonal Potentials [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1988
The short and long periodic perturbations and secular perturbation due to the geopotentials of degree J2 and J3 which affect orbital elements of a near-circular satellite are obtained by the analytical method.

Orbital elements of the material surrounding comet 67P/Churyumov-Gerasimenko

open access: yes, 2015
We investigate the dust coma within the Hill sphere of comet 67P/Churyumov-Gerasimenko. Aims. We aim to determine osculating orbital elements for individual distinguishable but unresolved slow-moving grains in the vicinity of the nucleus.

Vortex beam: generation and detection of orbital angular momentum [Invited]

open access: yesChinese Optics Letters (COL), 2022
Recent advances in the research of vortex beams, structured beams carrying orbital angular momentum (OAM), have revolutionized the applications of light beams, such as advanced optical manipulations, high-capacity optical communications, and super ...
