论文摘要
最近的系外球星观测报告了大量的多个星际系统，其中一些行星在共鸣链中。共振系统与非谐振系统的比例提供了有关其形成历史的线索。我们通过考虑行星质量和恒星质量的长期演变以及使用轨道计算，研究了行星在谐振链中的轨道稳定性。我们发现，虽然谐振链稳定，但可以通过$ \ sim $ 10％的行星质量变化来破坏它们的稳定。由于光蒸发，大气中的逃生可能会发生这种质量演变。我们还发现，通过$ \ lyssim1 $％的出色质量损失可能会破坏谐振连锁，这将由恒星风或冠状质量弹射来解释。行星和恒星的长期质量变化在包括超级诞生的行星系统的轨道发展中起着重要作用。
Recent exoplanet observations reported a large number of multiple-planet systems, in which some of the planets are in a chain of resonances. The fraction of resonant systems to non-resonant systems provides clues about their formation history. We investigated the orbital stability of planets in resonant chains by considering the long-term evolution of planetary mass and stellar mass and using orbital calculations. We found that while resonant chains were stable, they can be destabilized by a change of $\sim$10% in planetary mass. Such a mass evolution can occur by atmospheric escape due to photoevaporation. We also found that resonant chains can be broken by a stellar mass loss of $\lesssim1$%, which would be explained by stellar winds or coronal mass ejections. The long-term mass change of planets and stars plays an important role in the orbital evolutions of planetary systems including super-Earths.
