The Use of Geocentric Variables to Search for Meteoroid Streams and Their ParentsA set of geocentric variables suitable for the identification of meteoroid streams has been recently proposed and successfully applied to photographic meteor orbits. We describe these variables and the secular invariance of some of them, and discuss their use to improve the search for meteoroid stream parents.作者: Anticlimax 時間: 2025-3-22 15:02 作者: 吹牛大王 時間: 2025-3-22 19:13
Periodic Orbits Around a Massive Straight SegmentIn this paper, we consider the motion of a particle under the gravitational field of a massive straight segment This model is used as an approximation to the gravitational field of irregular shaped bodies, such as asteroids, comet nuclei and planets’s moons. For this potential, we find several families of periodic orbits and bifurcations.作者: 搜尋 時間: 2025-3-22 22:43

Dimensionality of Stable and Unstable Directions in the Gravitational ,-Boby Problem, there are about 1.2. unstable directions out of 3.. Issues of dimensionality arise when the tools of ergodic studies are brought to bear on the problem of trajectory separation. A method of estimating the rate of trajectory separation based on matrix descriptions is presented in this note.
