正则静态黑洞的薄吸积盘

依照Penrose的宇宙检察猜想,自然界不存在裸奇性.所以,值得进一步考虑的是自然界根本不存在奇性.讨论了没有奇点的正则黑洞,并研究史瓦西黑洞和正则黑洞在天体物理学中的区别.研究围绕正则黑洞的薄吸积盘,比较了不同正则黑洞之间薄吸积盘的能量通量,辐射温度和吸积效率.结果显示,正则黑洞薄吸积盘内的相互作用比史瓦西的更加强.此外,随着正则黑洞质量不断地减少,薄吸积盘会更有效地消耗能量.这些特征提供了一种区分出正则黑洞的可能性.

Thin accretion disk around regular black hole

The Penrose＇s cosmic censorship conjecture says that naked singularities do not exist in nature. So,it seems reasonable to further conjecture that not even a singularity exists in nature. In this paper,a regular black hole without singularity is studied in de- tail, especially on its thin accretion disk, energy flux, radiation temperature and accretion efficiency. It is found that the interaction of regular black hole is stronger than that of the Schwarzschild black hole. Furthermore, the thin accretion will be more efficiency to lost energy while the mass of black hole decreased. These particular properties may be used to distinguish between black holes.
