Optical Gravitational Lensing Experiment, Phase III

AST-0607070研究：普林斯顿大学PI：Bohdan Paczynski TITLE：光学引力透镜实验，第三阶段。普林斯顿大学的Bohdan Paczynski将继续进行光学引力透镜实验。这项针对透镜事件的调查通常每年确定约600个事件，迄今已检测到近3000个事件。OGLE已经发现了超过300,000颗变星，以及一些独特的太阳系外行星，并对大质量致密晕天体(MACHO)的存在(或不存在)施加了重要限制，MACHO是银河系光晕中一种被提议的暗物质类型。未来的观测将继续这些和其他类型的发现。数据将发布给更广泛的社区，供专业天文学家、业余天文学家和学生进行数据挖掘。特别是，OGLE是变星研究的宝贵资源，可用于广泛的天体物理研究。

AST-0607070INSTITUTION: Princeton UniversityPI: Bohdan PaczynskiTITLE: Optical Gravitational Lensing Experiment, Phase IIIABSTRACTDr. Bohdan Paczynski, at Princeton University, will continue the Optical Gravitational Lensing Experiment (OGLE). This survey for lensing events typically identifies some 600 events per year, with nearly 3000 events detected to-date. OGLE has identified over 300,000 variable stars, a number of unique extrasolar planets, and has placed important constraints on the presence (or absence) of massive compact halo objects (MACHOS), a proposed type of dark matter in the halo of the Galaxy. Future observations will continue these and other types of discoveries.The data are released to the broader community, for data mining by professional astronomers, amateur astronomers and students. In particular OGLE is a valuable resource for variable star studies that can be used in a broad range of astrophysical research.
