P6 5 Evidence for a Diamond Layer in the Mantle of Neptune

Abstract

This paper explores the idea of diamond formation in gas giants. We apply terrestrial experimentaldata to the theoretical atmospheric composition and structure of Neptune. We conclude that it isfeasible that a solid layer of diamond could form in the conditions on Neptune, completely replacingthe layer of liquid methane predicted on the planet. This is not in line with current theories butdoes have some supporting evidence from the scientic community, and further observational datais required.
