  张辉,2008年获南京大学天文系博士学位,2014年澳大利亚新南威尔士大学高级访问学者,目前为南京大学天文与空间科学学院副教授。主要从事太阳系外行星的形成与演化相关的研究,内容包括行星与气体盘相互作用的流体数值模拟大视场高精度测光巡天方法系外行星候选体的高精度视向速度证认以及行星大样本统计等。2011年开始参与中国南极天文973项目,负责其中太阳系外行星的观测策略和数据处理工作。目前发现太阳系外行星候选体100余颗,发表相关SCI论文20余篇。 

  报告摘要: 

  While the space based exoplanet survey projects (e.g. Kepler) have achieved great success, there is still valuable exoplanetary science that can be done from the ground. This is especially important at some unique sites. Dome A, the highest point of the Antarctic plateau, is one of these sites. In 2008, China established a scientific site at Dome A. Now, in a significant collaboration with Australian astronomers, a large survey project has been ongoing there for several years. This is the Antarctic Survey Telescope (AST3) project, consisting of three 0.5m telescopes located at Dome A. The exoplanet searching program is one of the two major scientific aims of AST3. I will briefly outline this project and introduce the progress of the exoplanet survey in details. It will cover the exoplanet scientific goals, instruments, designs of survey strategy, data reduction pipeline and exoplanet candidates we found within TESS’s Southern Continuous Viewing Zone.
