报告题目：Direct Imaging Research of Exoplanets & Solar Scientific Observations

　　报 告 人：窦江培副研究员（南京天光所）

　　摘    要：Until now over 1800 exoplanets has been discovered mostly by the indirect detection methods such as radial velocity and transiting approaches. Among them, few were directly imaged. However, the direct image research of an exoplanetwill finally allow the characterization ofits physical parameters such as atmosphere and composition. The direct imaging of an Earth-like exoplanets in the habitable zone of a solar type star and atmosphere spectroscopy analysis will be one of the most effective methods to detect exo-life signals, which will finally answer “Are we alone in the universe?”, which is one of the most fundamental scientific questions.

　　In this presentation, we will report the recent observational results by using our Extreme Adaptive Optics (Ex-AO) as a visiting instrument on ESO’s 3.58-meter NTT telescope at LSO, which has demonstrated the Ex-AO can be immediately used for the scientific research of exoplanets. Meanwhile, the technical requirements and the dedicated instrument, including the going on ground-based projects of EDICT (young giant exoplanets detection program) and the future space program of JEEEDIS (Earth-like exoplanets detection program), will be presented.

　　Finally, we will also report the latest results of Solar diffraction-limited imaging observation over a large field of view and some pilot work on the development of IFU spectro-polarimeter for high-cadence and high-fidelity solar magnetic field measurement.
