土星共轨卫星：先天形成
Coorbital Satellites of Saturn: Congenital Formation
摘要：
土星是目前已知的唯一拥有共轨卫星系统的行星。在目前的工作中，我们研究了质量吸积过程作为一种可能的机制，共轨卫星的形成。所考虑的系统是由土星，一个原卫星和一个云的微行星分布在共轨区域周围的三角拉格朗日点。原卫星的相对质量是土星质量的10^-6，而每一个微行星云的相对质量有三种情况，分别是土星质量的10^-14、10^-13和10^-12。在模拟中，每个微行星云由10^3、5 x 10^3或10^4个微行星组成。模拟结果显示，这些卫星的相对质量与土星系统中的卫星（10^-13 - 10^-9）的相对质量数量级相同。它们大多数呈马蹄形轨道，但也有相当一部分是L_4或L_5附近的蝌蚪轨道。因此，结果表明，这是一个合理的机制，形成共轨卫星。
英文摘要：
Saturn is the only known planet to have coorbital satellite systems. In the present work we studied the process of mass accretion as a possible mechanism for coorbital satellites formation. The system considered is composed of Saturn, a proto-satellite and a cloud of planetesimals distributed in the coorbital region around a triangular Lagrangian point. The adopted relative mass for the proto-satellite was 10^-6 of Saturn's mass and for each planetesimal of the cloud three cases of relative mass were considered, 10^-14, 10^-13 and 10^-12 masses of Saturn. In the simulations each cloud of planetesimal was composed of 10^3, 5 x 10^3 or 10^4 planetesimals. The results of the simulations show the formation of coorbital satellites with relative masses of the same order of those found in the saturnian system (10^-13 - 10^-9). Most of them present horseshoe type orbits, but a significant part is in tadpole orbit around L_4 or L_5. Therefore, the results indicate that this is a plausible mechanism for the formation of coorbital satellites.
