Satellite OrbitsApogeesSynchronous SatellitesFirst a description is given of a new satellite system concept using highly eccentric inclined orbits, with special attention on orbit characteristics and related aspects and some impacts on satellite configuration and communication system. Following this, it is ...
Numerical experiments on planetary orbits in double stars This is a numerical study of orbits in the elliptic restricted three-body problem concerning the dependence of the critical orbits on the eccentricity of t... R Dvorak - 《Celestial Mechanics》 被引量: 86发表: 1984年 Laboratory-numerical ...
Satellite Communications Toolbox™ is a tool that provides standards-based tools for designing, simulating, and verifying satellite communications systems and links. The toolbox enables you to model and visualize satellite orbits and perform link analysis and access ...
NASA’s satellite found planet LP 890-9b, which is about 30% larger than Earth and orbits its sun in just 2.7 days. ULiège researchers used their telescopes in Spain to take a closer look at the planet. That’s when the stargazers(天文学家) discovered another planet, LP 890-9c, which...

Based on the location of Centaurus, Uklun can be located in the southern hemisphere of the celestial sky. The celestial hemisphere is equivalent to the hemispheres on Earth. Uklun is south of the Ecliptic. The Ecliptic is the path that the Earth takes as it orbits the Sun. As the Earth...
3d). As a result, along these high-symmetry directions the crossings are protected, leading to six inequivalent Dirac points emerging in the polariton spectrum—we call these satellite Dirac points (SDPs) to distinguish them from the CDPs. As we will see below, these SDPs belong to the type...
They think a warp or clump in the disk, located about as far from the binary as Neptune is from the Sun, causes this extra variation as it orbits. Vega completed her analysis of the U Mon system as a NASA Harriett G. Jenkins Predoctoral Fellow, a program funded by...

26/01/00 ON THE NATURE OF THE RING-LIKE STRUCTURE IN THE OUTER GALACTIC DISK We examine the tidal disruption of satellite galaxies in a cosmological simulation of the formation of a disk galaxy in the 螞CDM scenario. We find that the disruption of satellite galaxies in orbits roughly ...
