内太阳系特洛伊小行星的搜索策略

Search strategies for Trojan asteroids in the inner Solar System

M. Todd, D. M. Coward, M. G. Zadnik

摘要:

特洛伊小行星是一种小行星,它们与一颗行星共享围绕太阳的轨道,并围绕L4或L5拉格朗日稳定点进行平动。它们很重要,因为它们携带了早期太阳系形成的信息,当时天体之间的碰撞更为频繁。类地行星特洛伊的发现和研究将有助于约束内太阳系天体分布和相互作用的模型。我们提出了约束最佳搜索区域的模型,以及测量望远镜最大限度地提高探测内行星特洛伊的概率的策略。我们还考虑了探测盖亚卫星的影响,以及盖亚观测几何的局限性。

英文摘要:

Trojan asteroids are minor planets that share the orbit of a planet about the Sun and librate around the L4 or L5 Lagrangian points of stability. They are important because they carry information on early Solar System formation, when collisions between bodies were more frequent. Discovery and study of terrestrial planet Trojans will help constrain models for the distribution of bodies and interactions in the inner Solar System. We present models that constrain optimal search areas, and strategies for survey telescopes to maximize the probability of detecting inner planet Trojans. We also consider implications for detection with respect to the Gaia satellite, and limitations of Gaia's observing geometry.
