| Research Abstract |
It is known that the earth’s outer core is not a liquid of pure iron and includes a significant amount of light elements. In order to understand the light elements, we performed ab initio simulations using super computers and high-pressure experiments using diamond anvil cells. An assumption that silicon, oxygen, and sulfur are light elements in the outer core was excluded. It was expected that the outer core has carbon and hydrogen.
