论文摘要
许多热和超热的木星膨胀了半径，这意味着它们的内饰保留了地层的显着熵。这些热内部导致内部热通量增强，从下方撞击了大气。在这项工作中，我们研究了这种热内部对热和超热木星的大气循环和热结构的影响。为此，我们从热和超热木星的进化模型中纳入了人口水平的预测，作为其大气循环的一套通用循环模型（GCM）的输入，具有不同的半轴轴和表面重力。我们进行有或没有热内部的模拟，发现在可观察到的气氛中，在多达数百个开尔文的温度上存在明显的局部差异，并且在数百个M s $^{ - 1} $或更多的风速中存在明显的局部差异。这些差异在研究的整个参数状态中持续存在，并通过对光球压力的影响取决于表面重力。这些结果表明，热和超热木星的内部进化和大气热结构以及动力学是耦合的。结果，可能需要包括进化模型和GCM在内的联合方法对热和超热木星的大气循环做出可靠的预测。
Many hot and ultra-hot Jupiters have inflated radii, implying that their interiors retain significant entropy from formation. These hot interiors lead to an enhanced internal heat flux that impinges upon the atmosphere from below. In this work, we study the effect of this hot interior on the atmospheric circulation and thermal structure of hot and ultra-hot Jupiters. To do so, we incorporate the population-level predictions from evolutionary models of hot and ultra-hot Jupiters as input for a suite of General Circulation Models (GCMs) of their atmospheric circulation with varying semi-major axis and surface gravity. We conduct simulations with and without a hot interior, and find that there are significant local differences in temperature of up to hundreds of Kelvin and in wind speeds of hundreds of m s$^{-1}$ or more across the observable atmosphere. These differences persist throughout the parameter regime studied, and are dependent on surface gravity through the impact on photosphere pressure. These results imply that the internal evolution and atmospheric thermal structure and dynamics of hot and ultra-hot Jupiters are coupled. As a result, a joint approach including both evolutionary models and GCMs may be required to make robust predictions for the atmospheric circulation of hot and ultra-hot Jupiters.
