天王星和海王星的内部:目前的理解和开放的问题

The Interiors of Uranus and Neptune: Current Understanding and Open Questions

Ravit Helled, Jonathan J. ~Fortney

摘要:

天王星和海王星在我们的太阳系中形成了一个独特的行星类别。鉴于这一事实,以及类似质量的行星在其他行星系中的普遍存在,了解它们的内部结构和组成是至关重要的。然而,关于这些行星的开放性问题比答案更多。在这篇评论中,我们专注于我们不知道的关于天王星和海王星内部的事情,重点是为什么行星可能是不同的,而不是相同的。接下来,我们将总结有关行星内部结构和演化的知识。最后,我们确定的主题,应该进一步研究的理论前沿,以及所需的观测空间任务。

英文摘要:

Uranus and Neptune form a distinct class of planets in our solar system. Given this fact, and ubiquity of similar-mass planets in other planetary systems, it is essential to understand their interior structure and composition. However, there are more open questions regarding these planets than answers. In this review we concentrate on the things we do not know about the interiors of Uranus and Neptune with a focus on why the planets may be different, rather than the same. We next summarize the knowledge about the planets' internal structure and evolution. Finally, we identify the topics that should be investigated further on the theoretical front as well as required observations from space missions.
