Astrometric orbits of SB9 stars
, 2005 Hipparcos Intermediate Astrometric Data (IAD) have been used to derive astrometric orbital elements for spectroscopic binaries from the newly released Ninth Catalogue of Spectroscopic Binary Orbits (SB9).

New orbital elements of 5 interferometric double stars [PDF]
Serbian 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]
Journal 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.

Low-Trust Trajectory Design from LEO to GEO Using Reinforcement Learning [PDF]
علوم، فناوری و کاربردهای فضاییIn this paper, In the preliminary phase of space mission design, the selection of the spacecraft's trajectory is critical. This study simulates the dynamics of low-thrust orbital transfers within a two-dimensional orbital plane, employing a set of ...

NORAD TLE Conversion from Osculating Orbital Element [PDF]
Journal of Astronomy and Space Sciences, 2002 The NORAD type Two Line Element (TLE) was obtained from the osculating orbital elements by an iterative approximation procedure. The mathematical model was presented and computer program was developed for the conversion.

Asteroids Observed by The Sloan Digital Sky Survey [PDF]
, 2002 We announce the first public release of the SDSS Moving Object Catalog, with SDSS observations for 58,117 asteroids. The catalog lists astrometric and photometric data for moving objects observed prior to Dec 15, 2001, and also includes orbital elements ...

Secular Evolution of a Two-Planet System of Three Bodies with Variable Masses
UniverseA classical three-body problem with two planets moving around a central star of variable mass on quasi-periodic orbits is considered. The bodies are assumed to attract each other according to Newton’s law of universal gravitation. The star loses its mass

Apollo asteroids (1566) Icarus and 2007 MK6: Icarus family members?
, 2007 Although it is more complicated to search for near-Earth object (NEO) families than main belt asteroid (MBA) families, since differential orbital evolution within a NEO family can cause current orbital elements to drastically differ from each other, we ...
