论文摘要
超热木星（UHJS）的大气是在低光谱分辨率下检测分子和原子的主要目标。我们通过使用高温相关-K不透明度方案对包括超柔属物质（UV）吸收的物种进行这些行星的3D通用循环模型（GCM）来研究UHJS WASP-121B和WASP-189B的大气。然后将GCM结果在低光谱分辨率下进行后处理，并将其与可用数据进行比较。高分辨率结果与分子和原子模板交叉相关以产生模拟分子检测。我们的GCM模型产生的温度压力（T-P）结构趋势与以前的1D辐射式感染平衡模型相似。此外，紫外线不透度的包含大大塑造了UHJ大气的高海拔，低压区域的热和动力学特性，由于紫外线吸收而引起的急剧T-P反转。这表明光波长高分辨率观测值探测了动态不同的上层大气区域，而不是较深的喷射层。
The atmospheres of ultra hot Jupiters (UHJs) are prime targets for the detection of molecules and atoms at both low and high spectral resolution. We study the atmospheres of the UHJs WASP-121b and WASP-189b by performing 3D general circulation models (GCMs) of these planets using high temperature correlated-k opacity schemes with ultra-violet (UV) absorbing species included. The GCM results are then post-processed at low and high spectral resolutions and compared to available data. The high resolution results are cross-correlated with molecular and atomic templates to produce mock molecular detections. Our GCM models produce similar temperature-pressure (T-p) structure trends to previous 1D radiative-convective equilibrium models of UHJs. Furthermore, the inclusion of UV opacities greatly shapes the thermal and dynamical properties of the high-altitude, low-pressure regions of the UHJ atmospheres, with sharp T-p inversions due to the absorption of UV light. This suggests that optical wavelength, high-resolution observations probe a dynamically distinct upper atmospheric region, rather than the deeper jet forming layers.
