系外行星的探测和刻画(Exoplanet detection & characterization)

Planets are extremely faint compared to their host stars, so how to find them? Our group uses multiple indirect methods to detect and characterize planets around stars other than our Sun. In particular, together with Prof. Shude Mao, we are actively involved in the Korea Microlensing Telescope Network (KMTNet) project, which is the leading survey in detecting exoplanet via the microlensing method. Members of our Tsinghua team have led and contributed to the discovery of dozens of microlensing planets, including most of planets with planet-to-star mass ratio below ~10-4.

系外行星统计(Exoplanet statistics)

As shown by the figure above, individual detection techniques have their own limitations, so how to combine them and derive the intrinsic distribution of planets across the whole parameter space? Our team models the observational bias and survey incompleteness and recovers the underlying planet distribution, especially key questions related to planet multiplicity. We then use these results to test and constrain the theoretical models of planet formation.

Other Projects

Our team is interested in a broad range of theoretical and observational topics:
  • Compact object search via microlensing, astrometry, etc;
  • Few-body dynamics;
  • Other applications of microlensing than exoplanet;
  • Time domain astronomy;
  • ...
