一个均匀、不旋转、无压力的球体应该会因静止而在重力作用下塌陷。结果表明，各向异性引力场使初始偏心率稳定增加：初始扁球体趋向圆盘，初始长球体趋向纺锤体。计算一系列初始偏心率的数值结果。
A uniform, non-rotating, pressure-free spheroid is supposed to collapse gravitationally from rest. It is shown that the initial eccentricity is steadily increased by the anisotropic gravitational field : an initially oblate spheroid tends toward a disk, and an initially prolate spheroid toward a spindle. Numerical results are computed for a series of initial eccentricities.
