David Rice, Jason Steffen (both Physics and Astronomy) and their collaborator, Chenliang Huang from the University of Arizona, published an open-source software package that models the interior structures of rocky and water-rich planets. This code was designed to facilitate the collaboration between UNLV astronomers who study extrasolar planets, and UNLV physicists who study the properties of matter under high-pressure and high-temperature conditions. The paper outlining this code and its capabilities will appear in the Monthly Notices of the Royal Astronomical Society. Rice is an astronomy graduate student, while Steffen is his advisor.
