黑洞吸积的后牛顿声界

SOUND HORIZON OF ACCRETION ONTO A BLACK HOLE IN POST-NEWTON

本文研究了后牛顿近似下黑洞吸积的跨声速解,在牛顿势的假定下,分析了旋转黑洞吸积的声界性质。在考虑黑洞的奇点效应后,结果与卢炬甫等结论一致。

In this paper, we study the transonic solution of accretion onto a black hole in post-Newton, we discuss the sonic point properties of accretion onto a rotation black hole in Newton gravitional potential. The consequence is identical to the one that have been studied by J. F. Lu et al. after the singular poiont effect considered.
