Title: Imaging the Exoplanets


Imaging method is a viable pathway to detect exoplanet and characterize the planetary atmosphere. However, imaging exoplanets is challenging due to the small angular separation and extreme intensity contrast between the exoplanet and its host star (~1e-4 for self-luminous giant planets and ~1e-10 for rocky planets). Collaborating with Nanjing Institute of Astronomical Optics & Technology, Chinese Academy of Sciences, we are developing next generation Adaptive Optic (AO) systems aiming to detect and characterize rocky exoplanets. The design of AO systems, the observation strategy, data reduction techniques, and the method for retrieving physical properties of imaged objects will be introduced in this talk.
