该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。这个计划将集中于发现和描述太阳邻域中较暗的成员: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(近邻恒星研究联盟)工作的核心科学目标是:(1)揭示新的近邻恒星和年轻恒星,其自身运动速度为3角秒/年,降至无法检测的水平;(2)在10个PC内完成所有恒星的普查;(3)在25个PC内大幅增加红矮星和白矮星的样本。以及(4)从天体测量学角度搜索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专业和业余天文学家的资源,包括近10秒的天体普查和最近的百个恒星系统列表,在2008年的前九个月产生了超过13000个服务器请求到RECONS网站。最近又增加了一个视差数据库。该项目将支持1名博士后研究员、2名研究生和1名本科生。
英文摘要
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.
