Currently, there are more than 100 confirmed multiple-planet systems. Moreover, a recent study by Kepler has identified 361 multiple-planet candidate systems. Investigating these systems would give us an important clue in understanding formation and evolution of planetary systems. In such multiple-planet systems, secular interactions among planets could play a significant role in determining th...

Ostro (JPL/Caltech) Radar delay-Doppler measurements are powerful for refining asteroid orbits because they have extremely fine fractional precision and are orthogonal to optical angle astrometry. Radar detection of a newly discovered near-Earth asteroid (NEA) secures its orbit and can add centuries to the interval over which its close Ear...

(1) The intensity of cosmic rays is practically independent of time. This fact indicates that the origin of these rays can be sought neither in the sun nor in any of the objects of our own Milky Way. (2) The decrease in intensity of cosmic rays in equatorial regions has successfully been explained by assuming that at least a part of the rays consists of very energetic, positively or negatively ...
متن کاملThe Unified Astronomy Thesaurus: Semantic Metadata for Astronomy and Astrophysics
Several different controlled vocabularies have been developed and used by the astronomical community, each designed to serve a specific need and a specific group. The Unified Astronomy Thesaurus (UAT) attempts to provide a highly structured controlled vocabulary that will be relevant and useful across the entire discipline, regardless of content or platform. As two major use cases for the UAT i...
