Azimuthal anisotropy of stellar galactic disks

The ellipsoid of stellar random motions is a fundamental ingredient of galaxy dynamics. Yet it has long been difficult to constrain this component in disks others than the Milky...恒星随机运动椭球（ellipsoid of stellar random motions）是星系动力学的基本组成要素。然而长期以来，在除银河系之外的盘状星系中，对该组分进行约束始终面临挑战。
