Optical Gravitational Lensing Experiment, Phase III

AST-0607070机构：普林斯顿大学PI：Bohdan Paczynski标题：光学引力透镜实验，第三阶段普林斯顿大学的博丹·帕钦斯基将继续进行光学引力透镜实验（OGLE）。 这种对透镜事件的调查通常每年识别约600个事件，迄今为止检测到近3000个事件。 OGLE已经识别了超过30万颗变星，一些独特的太阳系外行星，并对存在（或不存在）大质量致密晕天体（Mass Compact Halo Objects，简称Mass）提出了重要的限制，Mass致密晕天体是银河系晕中的一种暗物质。 未来的观测将继续这些和其他类型的发现。数据将向更广泛的社区发布，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是一个宝贵的资源，可变星星的研究，可用于广泛的天体物理学研究。

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.
