缓变动态Kerr黑洞视界附近的辐射能通量和辐射功率

采用黑洞的薄膜模型和局域热平衡的假定,研究缓变动态Kerr黑洞视界附近的辐射能通量和辐射功率,得到了缓变动态Kerr黑洞的热辐射满足广义Stefan-Boltzmann定律的结论。当截断距离以及薄膜厚度取定后,Kerr黑洞视界附近标量场的辐射能通量与辐射功率不仅与黑洞的质量有关,还与黑洞的视界变化率有关,表明黑洞周围的引力场和视界的变化均对黑洞的热辐射产生影响。

The Radiation Energy Flux and the Radiation Power near the Event Horizon of Slowly Changing Kerr Black Hole

Using the thin film model of black hole and the supposition of part thermal balanced, we studied the radiation energy flux and the radiation power near the event horizon of slowly changing Kerr black hole. It is found that the thermal radiation of Kerr black hole always satisfies the generalized Stefan-Boltzmann law. When the cut-off distance and the thin film thickness are fixed, both the radiation energy flux and the radiation power of slowly changing Kerr black hole are related to the black hole mass and the black hole changing rate of the event horizon. It states that both the gravitational field and the changing rate of the event horizon will affect the thermal radiation of Kerr black hole.
