特洛伊小行星被认为是太阳系现存的最原始物质的化石。对这类小天体形成和演化的研究可以帮助我们理解太阳系大行星的形成和演化。目前在木星轨道的L4和L5位置上已发现的特洛伊小行星有六千多颗，海王星、火星和地球的轨道上也存在这类天体。本项目运用天体力学分析和数值模拟方法来研究特洛伊小行星的动力学起源以及演化。.特洛伊小行星的形成机制与大行星的形成/迁移、以及小行星带和柯伊伯带天体的轨道构型密切相关。对这种特殊类型的太阳系小天体的研究，有助于我们深入了解太阳系的起源和演化。

Trojan asteroids are considered as the primary fossils of solar system.Research for their formation and evolution can help us to understand the formation and evolution of the planets in solar system. There are more than 6000 Trojan asteriods found in the regions around the L4 and L5 Lagrangian points of Jupiter. Such bodies (Trojan asteriods) also exist on the orbits of Neptune, Mars and Earth. Their dynamical origin and evolution will be studied with the celestial mechanics and numerical method in this project..Trojan asteroids formation mechanisms are closely related to giant planet formation/migration and the orbital structure in the asteroid and Kuiper belts. The research for this kind of asteroids is helpful for us to understand the origin and evolution of the solar system.
