In this project, Dr. Fortney and his collaborators will create a new code to compute the thermal evolution histories of Neptune-class and Jupiter-class giant planets. Within the solar system, this standard theory fails to explain the current luminosity of three of the four giant planets. The main strength of this new code will be its ability to treat the evolution of planets with inhomogeneous interior structures. The new planetary code will include high-pressure equations of state, molecular and atomic opacities, irradiated model atmospheres, and advanced treatments of convection in regions of composition gradients. It is anticipated that the work will improve our understanding of planets in our solar system and around other stars. The team will release the new codes code to the community of planetary science researchers. This project will also support efforts to inform the public through public presentations and on the Internet.

在这个项目中，福特尼博士和他的合作者将创建一个新的代码来计算海王星级和木星级巨行星的热演化历史。在太阳系内，这个标准理论无法解释四颗巨行星中三颗的当前亮度。这个新代码的主要优势在于它能够处理内部结构不均匀的行星的演化。新的行星代码将包括高压状态方程，分子和原子的不透明性，辐射模型大气，以及成分梯度区域对流的高级处理。预计这项工作将提高我们对太阳系和其他恒星周围行星的理解。该团队将向行星科学研究人员社区发布新的代码。该项目还将支持通过公开演讲和互联网向公众宣传的工作。
