题目：Extreme Exoplanetary Systems: From Hot Jupiters to Tatooine Planets

　　报告人：Professor Dong Lai(Cornell University)

　　摘要：Observations over the last decade have revealed exoplanetary systems that are completely different from our own Solar System. These extreme planetary systems are changing our view of planetary formation. They raise many puzzles and require new theoretical works for their proper understanding. I will review some of the recent puzzles and discuss the possible physical processes at work in these systems.
