LEXEN: A Search for Extra-Solar Planets From the Southern Hemisphere

威廉·科克伦，德克萨斯大学奥斯汀分校，电话：98-08980Cochran和Hatzes将继续欧洲南方天文台的行星巡天计划，这是一项高精度径向速度巡天计划，通过探测在附近太阳型恒星轨道上运行的类木质量行星，来探索太阳系以外的行星环境。这项调查将改进具有行星系统的太阳型恒星的比例的统计数据，以及这些系统的多样性。该奖项是通过NSF的极端环境下的生命特别竞赛获得的，由数学和物理科学理事会的天文科学部和多学科活动办公室参与。

Cochran, WilliamUniversity of Texas, AustinAST 98-08980Drs. Cochran and Hatzes will continue the European Southern Observatory Planetary Survey, a high precision radial velocity survey to explore planetary environments beyond our solar system by detecting Jovian-mass planets in orbit around nearby solar- type stars. The survey will yield improved statistics on the fraction of solar-type stars with planetary systems, and the diversity of these systems. This award is made through NSF's special competition for Life in Extreme Environments, with participation by the Division of Astronomical Sciences and the Office of Multidisciplinary Activities in the Directorate for Mathematical and Physical Sciences.
