标题： Impacts of Tidal Locking on Magnetospheric Energy Input to Exoplanet Atmospheres

摘要： 我们研究了行星共转对系外行星磁层-电离层系统内能量耗散的影响。使用磁流体力学模拟，我们发现与具有相同磁场强度的快速旋转行星相比，潮汐锁定的系外行星具有更高的极隙电位（CPCP），这证实了先前的研究。我们的模拟表明，对于给定的行星际磁场，在共转周期增加的情况下，CPCP也会更高。值得注意的是，这种在CPCP上的差异在一系列太阳风条件下持续存在，包括热木星所经历的极端环境。此外，我们观察到共转的变化对地球大小的行星的CPCP影响较小。这些结果强调了共转动力学和行星尺寸在理解系外行星如何与其恒星环境相互作用中的重要性。 显示英文摘要

摘要： We investigate the effect of planetary corotation on energy dissipation within the magnetosphere-ionosphere system of exoplanets. Using MHD simulations, we find that tidally locked exoplanets have a higher cross-polar cap potential (CPCP) compared to fast-rotating planets with the same magnetic field strength, confirming previous studies. Our simulations show that for a given interplanetary magnetic field, an increase in corotation period leads to a higher CPCP. Notably, this difference in CPCP between tidally locked and rotating planets persists across a range of solar wind conditions, including extreme environments such as those experienced by hot Jupiters. Furthermore, we observe that variations in corotation have little impact on CPCP for Earth-sized planets. These results underscore the significance of both corotation dynamics and planetary size in understanding how exoplanets interact with their stellar environments.
