研究了非束缚超高速星的角位置和角间距的分布。HVS在3σ水平上具有空间各向异性。空间各向异性是显着的银河经度，而不是在纬度，并列入较低的速度，可能约束HVS降低的意义的各向异性。我们将讨论如何观察到的分布HVS可能与其起源。未来，测量南方天空中HVS的分布将对空间各向异性和HVS的起源提供额外的约束。
We study the distribution of angular positions and angular separations of unbound hypervelocity stars (HVSs). HVSs are spatially anisotropic at the 3σ level. The spatial anisotropy is significant in Galactic longitude, not in latitude, and the inclusion of lower velocity, possibly bound HVSs reduces the significance of the anisotropy. We discuss how the observed distribution of HVSs may be linked to their origin. In the future, measuring the distribution of HVSs in the southern sky will provide additional constraints on the spatial anisotropy and the origin of HVSs.
