SIM PlanetQuest:最有前途的近期技术,以检测,发现质量,并确定附近可居住行星的三维轨道
SIM PlanetQuest: The Most Promising Near-Term Technique to Detect, Find Masses, and Determine Three-Dimensional Orbits of Nearby Habitable Planets
摘要:
过去两次天文学和天体物理学十年巡天建议完成一项天基干涉测量任务,即今天所称的SIM PlanetQuest,因为它具有探测和确定附近岩石行星特征的独特能力(Bahcall 1991年,McKee & Taylor 2001年),并对天体物理学中的一系列广泛问题作出了贡献。美国国家研究委员会的许多委员会以及NASA路线图也同样强调SIM是一项可以检测和表征附近恒星周围岩石行星的技术,并且在技术上已经准备就绪。迄今为止,SIM仍然是唯一有能力探测和确认附近太阳型恒星宜居带中岩石行星的方案。此外,SIM测量了附近恒星(25 pc以内)周围适居行星的质量和三维轨道;这些恒星是唯一可以用其他技术跟踪的恒星,例如天基光谱学,地基干涉测量,当然还有TPF。
英文摘要:
The past two Decadal Surveys in Astronomy and Astrophysics recommended the completion of a space-based interferometry mission, known today as SIM PlanetQuest, for its unique ability to detect and characterize nearby rocky planets (Bahcall 1991, McKee & Taylor 2001), as well as contributions to a broad range of problems in astrophysics. Numerous committees of the National Research Council as well as NASA Roadmaps have similarly highlighted SIM as the one technology that offers detection and characterization of rocky planets around nearby stars and which is technically ready. To date, SIM remains the only program with the capability of detecting and confirming rocky planets in the habitable zones of nearby solar-type stars. Moreover, SIM measures masses and three-dimensional orbits of habitable planets around nearby stars (within 25 pc); these are the only stars for which follow-up by other techniques is feasible, such as space-based spectroscopy, ground-based interferometry, and of course TPF.
