牛顿引力中均匀旋转的均匀环

Uniformly Rotating Homogeneous Rings in Newtonian Gravity

Stefan Horatschek, David Petroff

摘要:

本文描述了一种处理牛顿引力中无中心体均匀旋转圆环的解析方法。我们采用了一系列的展开式的薄环极限和使用的事实,在这个极限的横截面的环趋于一个圆。这些系数原则上可以确定到任意阶。结果在这里提出的第20阶,并与数值结果进行比较。

英文摘要:

In this paper, we describe an analytical method for treating uniformly rotating homogeneous rings without a central body in Newtonian gravity. We employ series expansions about the thin ring limit and use the fact that in this limit the cross-section of the ring tends to a circle. The coefficients can in principle be determined up to an arbitrary order. Results are presented here to the 20th order and compared with numerical results.
