AI 中文摘要
我们重新审视了行星哈密顿量在轨道小偏心率和相互倾角下的经典展开,给出了完全基于向量形式主义的推导。我们证明了摄动函数的长期部分以及任何其他傅里叶谐波都可以用位于系统不变平面内的向量的标量积来表示。此外,我们展示了如何用轨道的角动量和偏心率向量来表示任何这样的项。
英文摘要
We revisit the classical expansion of the planetary Hamiltonian for small eccentricities and mutual inclinations of the orbits, presenting a derivation based entirely on vector formalism. We demonstrate that the secular part of the disturbing function, as well as any other Fourier harmonic, can be expressed in terms of scalar products of vectors lying in the system's invariant plane. Furthermore, we show how to express any such term using the angular momentum and eccentricity vectors of the orbits.
