Outline of Final Research Achievements |
High resolution observations of protoplanetary disks are now available with large telescopes and many protoplanetary disks show various structures. The goal of this research is to develope the methods to derive implications on physical status of protoplanetary disks and on planet formation processes from such observations. From the modeling work of the disk around HD 142527, we have found that there is a location in the disk where the dust particles are strongly concentrated. In the work on the shape of the gap structures produced by a planet embedded in the disk, our group is one of the first to derive the estimate of the planet mass in the disk around the HL Tau, in which several ring-like structures are found in the ALMA long-baseline campaign observations. In the work of linear stability analyses of Rossby wave instability, we have derived the marginally stable conditions of the instability, which have been a mystery over several decades.
