Orbital Architectures of Planet-Hosting Multiple-Star Systems

该项目包括通过检查开普勒系外行星调查中多恒星系统的轨道，探索恒星伴星对行星系统的影响。宽系统的轨道运动可以用盖亚宇宙飞船测量的超精密天体测量来分析。更紧密的双星可以通过凯克望远镜使用激光导星自适应光学系统进行观测来监测。对大量双星样本数据的分析应该有助于回答一些问题，比如某些轨道偏心率或恒星和行星平面之间的排列是否为行星的形成和生存提供了更有利的环境。

The project involves exploring the influence that stellar companions have on planetary systems by examining the orbits of multiple-star systems from the Kepler exoplanet survey. The orbital motion of wide systems can be analysed using ultra-precise astrometry measured by the Gaia spacecraft. Tighter binaries can be monitored by taking observations from the Keck Telescope using laser guide star adaptive optics. Analysis of data from a large sample of binaries should help to answer questions like whether certain orbital eccentricities or perhaps alignment between stellar and planetary planes provide more favourable environments for planet formation and survival.
