论文摘要
表征可居住的系外行星和/或其卫星至关重要。在这里，我们显示了磁场拓扑建模的结果，该模型表明，陆生外球星 - 外神体耦合磁层耦合在一起，以保护外部球星和外观的早期大气。当外部磁层在系外行星的磁层腔内时，Exomoon磁层的作用就像一种保护性磁性气泡，在日子越过时，在月球处时会面对恒星风。此外，磁重新连接将为早期系外行星和Exomoon之间的大气交换创造关键途径。当Exomoon的磁层不在外部球星的磁层之外时，它将成为抵抗强风的第一道防线，从而减少了系外行星对空间的大气损失。简短地讨论了这种类型的外事物如何修改磁化系外行星的无线电排放。
Characterizing habitable exoplanets and/or their moons is of paramount importance. Here we show the results of our magnetic field topological modeling which demonstrate that terrestrial exoplanet-exomoon coupled magnetospheres work together to protect the early atmospheres of both the exoplanet and the exomoon. When exomoon magnetospheres are within the exoplanet's magnetospheric cavity, the exomoon magnetosphere acts like a protective magnetic bubble providing an additional magnetopause confronting the stellar winds when the moon is on the dayside. In addition, magnetic reconnection would create a critical pathway for the atmosphere exchange between the early exoplanet and exomoon. When the exomoon's magnetosphere is outside of the exoplanet's magnetosphere it then becomes the first line of defense against strong stellar winds, reducing the exoplanet's atmospheric loss to space. A brief discussion is given on how this type of exomoon would modify radio emissions from magnetized exoplanets.
