時間/地點: 2017-10-20 14:00 [S4-1013]

摘要:

Current detection of exoplanets is mostly obtained at optical and near IR wavelengths toward disks where dense gas has been dissipated. In order to look for planets at earlier evolutionary stage, indirect evidences are invoked, such as rings of dust free region within dense disks, or spiral patterns. With the starting of ALMA early science observations, these indirect evidences at the millimeter (mm) and sub-mmm wavelengths have been detected in several disks. In this talk, I will present my recent studies on the asymmetric features using the ALMA and discuss the applications.
