在封闭系统中,潮汐扰动是否有必要超越实际质量近似?

Is it necessary to go beyond the ponctual mass approximation for tidal perturber in close systems?

Stephane Mathis, Christophe Le Poncin-lafitte

摘要:

随着非常接近的恒星行星系统的发现,行星轨道有时在几个恒星半径,但也与众所周知的情况下,在我们的太阳系中,天然卫星是非常接近他们的母行星的潮汐扰动(分别是母恒星或行星,当我们研究密切的行星或天然卫星动力学)的ponctual质量近似的有效性进行了检查。在这篇简短的论文中,我们认为这是有问题的,使用结果来自一个完整的形式主义,允许处理扩展机构之间的潮汐相互作用。我们专注于它的应用程序的一个简化的配置。

英文摘要:

With the discoveries of very close star-planet systems with planet orbiting sometimes at several star radius but also with well-known situations in our solar system where natural satellites are very close to their parent planet the validity of the ponctual mass approximation for the tidal perturber (respectively the parent star or planet when we study the close planet or natural satellite dynamics) has to be examined. In this short paper, we consider this problematic using results coming from a complete formalism that allows to treat the tidal interaction between extended bodies. We focus on its application to a simplified configuration.
