摘要:

帕洛玛高精度天体测量搜索系外行星系统(Palomar High-precision Astrometric Search for Exoplanet Systems,PHASES)监测了51个亚弧秒双星系统,以确定精确的双星轨道,研究三重和四重恒星系统的几何形状,并发现以前未知的微弱天体测量伴星,小至巨行星。从2002年到2008年年底,帕洛玛试验台干涉仪(PTI)停止正常运行的相位测量。本文用凯克自适应光学测量了几种相位目标的红外差示光度。

英文摘要:

The Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES) monitored 51 sub-arcsecond binary systems to determine precision binary orbits, study the geometries of triple and quadruple star systems, and discover previously unknown faint astrometric companions as small as giant planets. PHASES measurements made with the Palomar Testbed Interferometer (PTI) from 2002 until PTI ceased normal operations in late 2008 are presented. Infrared differential photometry of several PHASES targets were measured with Keck Adaptive Optics and are presented.
