I will present our recent research highlights on planetary systems.

The first is the Period-Ratio vs Mass-Ratio Correlation of multiple planetary systems we established in Jiang et al. (2015) MNRAS Letters.

The 2nd one is that, through transit observations, we obtain a new orbital decay rate of the Planet WASP-43b. This new value solves the contradiction between the theory and observations, and thus is a very important finding, as commented by the anonymous referee of AJ (

The implications of the above two will be given. If time is allowed, the current status of our NETS Project will be reviewed.
