Research Objectives

By gathering methods for observation, theory and experimentation, we aim to resolve all questions about the processes of the formation of planets from disks. We will clear up the details of the structure of a disk with 0.01 arc second resolutions provided by ALMA by getting into the area which forms a terrestrial planet. Meanwhile, we conduct infrared observation of disks in various developing stages. With the data of multiple wavelengths, we investigate the mutual evolution between three essentials (gas, refractory dust and icy dust) which form disk materials under these circumstances from both the observational and theoretical sides. Moreover, using the theory with simulation and experimenting in a cool environment, we refine the dust accumulation theory which is the most important step in the formation of planets. By comparing this data to the observation results, we are able to understand the steps of the growth process of dust into planets in full.
