Prospects of Disk Structure Observations for Young Protoplanetary Disks

Recent ALMA observations have revealed that protoplanetary disks are full of structures such as rings, gaps and spirals. However, it is not clear when and how such structures are formed. Ring / Gap structures are found in some Class I or deeply embedded sources such as HL Tau or WL 17. This indicates that planets may be formed at the very early stages or there may be some other mechanisms associated with the early stage of disk formation. In this talk, we present a model that ring-like structures can be formed at the early stages of disk formation and evolution if the large dust grains are present and disk wind is at work. We show that various structures may be formed depending on the physical parameters of the disk, and discuss future prospects on imaging observations of young disks.
