Abstract

Asteroid 216-Kleopatra presents a ham-bone shape, that is to say, it is quite elongated body with two protuberances on its end-points, which makes of it the perfect candidate to model its shape and mass distribution by a Dipole-Segment, consisting on a massive segment with two spherical masses at the end-points of the rod and that is rotating about its center of mass with uniform velocity. Once obtained an approximation of the actual values of the involved parameters from recent results of Burov and coworkers, we obtain the complete map of families of symmetric periodic orbits, and describe the orbits of the different families, its parametric evolution, stability and also we compute the heteroclinic orbits connecting unstable isosceles equilibria.

用偶极段模拟 216-Kleopatra 小行星周围的周期轨道

小行星 216-Kleopatra 呈 "火腿骨 "状，也就是说，它是一个相当细长的天体，在其端点上有两个突起物，这使它成为用偶极子段来模拟其形状和质量分布的最佳候选天体，偶极子段由一个大质量段组成，在杆的端点上有两个球形质量块，并以均匀的速度围绕其质量中心旋转。从布罗夫和同事的最新研究成果中获得相关参数实际值的近似值后，我们得到了对称周期轨道族的完整图谱，并描述了不同族的轨道、其参数演变、稳定性，还计算了连接不稳定等腰平衡点的异质轨道。

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
