| Outline of Final Research Achievements |
Our group studied various subjects related to the planet formation process in a protoplanetary disk. Major accomplishments achieved by our collaborations between astronomical observations, theories and impact experiments are as follows: (1) High resolution observations with ALMA and Subaru telescope have revealed that asymmetric structure is quite common in a protoplanetary disk. The regions of dust concentration in such structure may be responsible for the formation of rocky planetesimals. (2) Our theories on planetary gaps show that the ring-like features seen in several protoplanetary disks with different ages can be explained by a gap carved by a protoplanet, suggesting that a planetary system may form in various modes with different timescales. (3) Modeling of chemical reaction network in the formation site of a star-disk system has successfully reproduced spatial distributions and relative abundances of gas molecules, including HDO and N2H+, in a protoplanetary disk.
