标题： Diurnal Thermal Tides in a Non-synchronized Hot Jupiter

摘要： 我们进行了一项线性分析，以研究未同步的热木星对恒星辐射的动力学响应。 在这项工作中，我们考虑了恒星辐射的昼夜傅里叶谐波，该谐波作用于一颗无云且无风的热木星的辐射层顶部。 在科里奥利力不存在的情况下，当热强迫周期长于行星表面声波穿越时间时，昼夜热强迫可以激发向行星内部传播的内部波。 当考虑到科里奥利效应时，与纬度相关的恒星加热可以根据行星的非同步性激发弱内部波（g模）和/或强斜压罗斯贝波（浮力r模）。 当行星自转速度比其轨道运动快（即反向热强迫）时，这些波携带负角动量，并在从辐射区上层向下传播时因辐射损失而阻尼。 因此，角动量从辐射区的下层传递到上层，并产生垂直剪切。 我们根据HD 209458b的参数估计了不同自转周期产生的内禀转矩。 显示英文摘要

摘要： We perform a linear analysis to investigate the dynamical response of a non-synchronized hot Jupiter to stellar irradiation. In this work, we consider the diurnal Fourier harmonic of the stellar irradiation acting at the top of a radiative layer of a hot Jupiter with no clouds and winds. In the absence of the Coriolis force, the diurnal thermal forcing can excite internal waves propagating into the planet's interior when the thermal forcing period is longer than the sound crossing time of the planet's surface. When the Coriolis effect is taken into consideration, the latitude-dependent stellar heating can excite weak internal waves (g modes) and/or strong baroclinic Rossby waves (buoyant r modes) depending on the asynchrony of the planet. When the planet spins faster than its orbital motion (i.e. retrograde thermal forcing), these waves carry negative angular momentum and are damped by radiative loss as they propagate downwards from the upper layer of the radiative zone. As a result, angular momentum is transferred from the lower layer of the radiative zone to the upper layer and generates a vertical shear. We estimate the resulting internal torques for different rotation periods based on the parameters of HD 209458b.
