散射型KBOs的原始轨道分布模拟

SIMULATION OF ORIGINAL DISTRIBUTION OF SKBOs

依据天体力学的N体问题模型,采用SWIFT程序包中的RMVS3积分器,对观测到的具有确定轨道根数的138个和虚拟的138×7个散射型KBOs进行了跨度为109年的轨道演化模拟,积分方向是逆着时间的方向.分析了10亿年前、4.5亿年前和当前散射型KBOs的轨道分布状态.

We made an ＂anti We made an - time＂ direction evolution simulation of 10^9 years long about the observed 138 SKBOs with reliable orbital elment and 138 × 7 clone SKBOs on the basis of the celestial mechanics model of the N -body problem , applying the RMVS3 integrator of the SWIFT package. The orbital distribution of the SKBOs at 10^9 years ago,4.5 × 10^8 years ago,and prensent has been analyzed.
