Damour-Ruffini Method, Hawking Radiation, Tortoise Coordinate Transformation, High-Dimensional Rotating Spacetime
Scientific paper
This study extends the classical Damour-Ruffini method and discusses Hawking radiation in a ( n + 4)-dimensional rotating black hole. Under the condition that the total energy and angular momentum of spacetime are conservative, but angular momentum a = J/ M of unit mass of the black hole is variable, taking into consideration the reaction of the radiation of the particle to the spacetime, a new Tortoise coordinate transformation and discuss the black hole radiation spectrum is discussed. The radiation spectrum that satisfies the unitary principle in the general case is derived.
