Research Objectives

We construct a formation model of habitable terrestrial planets which has enough accuracy to show or predict the initial conditions of the formation of the atmosphere and ocean, as well as the formation model of jovian planets which has the accuracy to be able to compare with the observed data in detail. In order to conduct this, we construct a disk structure model made from the simulation of magnetic turbulence fluid, radiation and dust growth based on the observational data for a protoplanetary disk in the primary condition of forming terrestrial planets. We also set the base on the N-body simulation or accurate celestial mechanics for the formation of the terrestrial planet. First, we present a theoretical prediction on the formation of jovian planets which includes all the observations and super earth data that has been collected. Through these comparisons and considerations, we construct a theoretical model to explain the terrestrial planets and point to theoretical estimates of habitable terrestrial planets. With this model, we actively participate in giving ideas to observation projects and conducting them.
