Formation of planetary architecture and the detection of exoplanets in Antarctic

Exoplanet detection and formation study is now one of the most active areas in astronomy.  Today, more than 1000 exoplanets are detected through various technics. These systems show some notable orbital architecture, indicating that they might have met some different dynamical history.  After a brief review of the recent progress in understanding the formation of planetary orbits, I will introduce some recent works in our group including some mechanisms for explaining the planet systems,  the identifications of several tens of Kepler planet through TTV, ect.  Also, the progress of planetary transit survey in Dome A, Antarctic is reported. With the CSTAR 2008's data, we identified 6 planet candidates, which remains to be confirmed.
