通过中透镜发现和研究邻近行星和双星系统

Discovery and Study of Nearby Planetary and Binary Systems Via Mesolensing

R. Di Stefano

摘要:

本文致力于探索如何通过观察它们作为引力透镜的作用来发现和研究附近(< 1- 2kpc)的行星和双星系统。透镜效应可以扩大可以系统研究的附近双星和行星的范围,包括黑暗和昏暗的双星,以及正面系统。与使用来自系统的光的更传统的研究一样,可以从透镜数据中提取轨道参数(包括总质量、质量比和轨道间隔)。我们讨论了所需的具体观测策略,以优化附近的行星和双星系统的发现和研究,通过观察他们的行动作为镜头。

英文摘要:

This paper is devoted to exploring how we can discover and study nearby (< 1-2 kpc) planetary and binary systems by observing their action as gravitational lenses. Lensing can extend the realm of nearby binaries and planets that can be systematically studied to include dark and dim binaries, and face-on systems. As with more traditional studies, which use light from the system, orbital parameters (including the total mass, mass ratio, and orbital separation) can be extracted from lensing data, Also in common with these traditional methods, individual systems can be targeted for study. We discuss the specific observing strategies needed in order to optimize the discovery and study of nearby planetary and binary systems by observing their actions as lenses.
