Outline of Final Research Achievements

At the early history of the solar system, molten iron alloy is separated from silicate mantle to form an iron core at the center of the protoplanets. We investigated this process by using high-pressure and high-temperature experiments combined with synchrotron X-ray micro computed tomography. We found that a permeable flow of liquid iron alloy through the crystalline silicate grain boundary is a dominant core-mantle separation process in the protpplanets with which the radius is smaller than several hundred km.
