论文摘要
众所周知，在地球和海王星之间具有半径的行星是迄今为止最常检测到的。为了将这些行星归类为陆地或气态，通常我们会转向质量 - 拉迪乌斯的关系和组成曲线，以确定这种行星是岩石或气态的可能性。尽管这些方法已将可能的过渡半径设置为约1.5 r $ _ {\ oplus} $，但我们不能指望地面和气态成分之间的任何变化将是一个急剧的截止，而构图策略的预测会导致行星在此偏移半径附近的行星指定模棱两可。在这项工作中，我们提出了过渡行星的3D一般循环模型，其中我们研究表面对可观察量的影响，例如纬度变化和日食深度。在讨论了该过渡行星的建模选择之前，我们介绍了对地球循环的最新GCM。最后，我们讨论了这项研究的结果，并探索了通过观察二次蚀的观察结果的前景。
It is well known that planets with radii between that of Earth and Neptune have been the most commonly detected to-date. To classify these planets as either terrestrial or gaseous, typically we turn to mass-radius relations and composition curves to determine the likelihood of such a planet being rocky or gaseous. While these methods have set a likely transition radius of approximately 1.5 R$_{\oplus}$, we cannot expect that any change between terrestrial and gaseous compositions will be a sharp cut-off, and composition curve predictions result in ambiguous designations for planets right near this transition radius. In this work we present 3D general circulation models of transition planets, wherein we study the effects of a surface on observable quantities such as the latitudinal variations and eclipse depths. We present our updated GCM, validated on the circulation of Earth, before discussing our modeling choices for this transition planet. Finally, we discuss the results of this study and explore the prospects of detecting the presence of a surface through observations of secondary eclipses in the future.
