Fantastic companions of giant planets and where to find them

点击翻译按钮获取中文摘要

The gas giants in the Solar System are hypothesized to have played important roles in the formation and habitability of the Earth. This project aims to put the Solar System in a broader context of the exoplanet demography. The expected outcomes of this project include: (1) a uniform sample of small planets discovered with the public Transiting Exoplanet Survey Satellite data; (2) detection of additional gas giants and in-depth characterisation of the best planetary systems; (3) occurrence rate of planetary systems cohosting both gas giant and small planets. This study will provide significant benefits for theoretically understanding the uniqueness of the Solar System, as well as the formation and evolution of planetary systems in general.
