Dr. Fischer will use the CHIRON spectrometer on the CTIO 1.5-m telescope to search for exoplanets via the radial velocity technique. She will target 30 bright late-type (G and K dwarf) stars with the goal of achieving 1 m/s measurement precision with new instrumentation after first testing it in a laboratory environment. The PI and her team will also develop a Doppler simulator to help determine the best possible observational precision. This work will train postdoctoral research associates, graduate and undergraduate students in research and instrumentation. The team will also work on the ?jitter? observational problem, which results from vertical atmospheric motions on small spatial scales, and if solved, would have wide applicability to other fields of astronomy. They will also conduct a hands-on ?Pathways to Science? program for school children, and help the Yale planetarium director develop a new show on exoplanets.

Fischer博士将使用CTIO 1.5米望远镜上的CHIRON光谱仪通过径向速度技术搜索系外行星。她将瞄准30颗明亮的晚型（G和K矮星）恒星，目标是在实验室环境中首次测试后，使用新仪器实现1 m/s的测量精度。PI和她的团队还将开发一个多普勒模拟器，以帮助确定最佳的观测精度。这项工作将培养博士后研究助理，研究生和本科生的研究和仪器。该团队还将致力于？抖动？这是一个由小尺度大气垂直运动引起的观测问题，如果得到解决，将对天文学的其他领域具有广泛的适用性。他们也会进行一个动手？科学之路？为学校的孩子们提供节目，并帮助耶鲁天文馆馆长开发一个关于系外行星的新节目。
