This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This program will focus on discovering and characterizing the fainter members of the solar neighborhood: red dwarfs, white dwarfs, brown dwarfs, and extrasolar planets. The core science goals of the RECONS (Research Consortium on Nearby Stars) effort at Georgia State University (GSU) are to (1) reveal new nearby and young stars with proper motions of 3 arcseconds/year down to undetectable levels, (2) move toward the completion of the census of all stars within 10 pc, (3) substantially increase the samples of red and white dwarfs within 25 pc, and (4) search astrometrically the nearest red and white dwarfs for brown dwarf and massive planetary companions with orbital periods up to a decade.The Broader Impacts of this program include resources for professional and amateur astronomers consisting of the Census of Objects Nearer than 10 Parsecs and List of the Nearest 100 Stellar Systems, generating more than 13000 server requests to the RECONS website in the first nine months of 2008. A parallax database has recently been added. The program will support 1 postdoctoral researcher, 2 graduate students, and 1 undergraduate student.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。这个项目将重点发现和描述太阳附近较暗的成员：红矮星、白矮星、棕矮星和太阳系外行星。佐治亚州立大学（GSU）的RECONS（近地恒星研究联盟）的核心科学目标是：(1)发现新的近地恒星和年轻的恒星，其正常运动速度为每年3角秒，降至无法探测的水平；(2)在10%的时间内完成对所有恒星的普查；(3)在25%的时间内大幅增加红白矮星的样本。(4)从天文测量上寻找距离最近的红矮星和白矮星，寻找轨道周期长达十年的褐矮星和大质量行星伴星。该计划的更广泛影响包括为专业和业余天文学家提供资源，包括近10秒差距的天体普查和最近的100个恒星系统列表，在2008年的前9个月，RECONS网站产生了超过13000个服务器请求。最近添加了视差数据库。资助博士后1人，研究生2人，本科生1人。
