This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Dr. Di Stefano and her co-investigators will use gravitational lensing to explore the local neighborhood of the Galaxy, the region within 1 kiloparsec. They will develop methods to identify local neutron stars, to measure their masses and transverse velocities, and to determine the fraction of them with companions, including planets. These studies will allow ongoing and new programs, including the planned Large Synoptic Survey Telescope, to discover and study hundreds of neutron stars. This work and parallel work may lead to the discovery of dozens of local black holes, as well as low-mass dwarf stars. Studies of planets around dwarf stars via gravitational lensing may have implications for our understanding of the ubiquity of life throughout the Universe.The Broader Impacts of this program include methods for automated detection and classification of variability, which has broad application, and training of graduate and undergraduate students.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。 Di Stefano 博士和她的合作研究人员将利用引力透镜来探索银河系的邻近区域，即 1 千秒差距以内的区域。 他们将开发方法来识别当地中子星，测量它们的质量和横向速度，并确定它们与包括行星在内的伴星的比例。这些研究将使正在进行的新项目（包括计划中的大型综合巡天望远镜）能够发现和研究数百颗中子星。这项工作和并行工作可能会导致发现数​​十个局部黑洞以及低质量矮星。 通过引力透镜对矮星周围行星的研究可能会对我们理解整个宇宙中生命的普遍性产生影响。该计划的更广泛影响包括自动检测和变异性分类的方法（具有广泛的应用）以及对研究生和本科生的培训。
