Quantum thermal effect of quasi-static evaporating charged black hole. (English) Zbl 0880.53065

Summary: The study of the quantum thermal effect of a non-static black hole is generalized to the spacetime with coordinates \((t,r)\) as variable. Tortoise coordinate equations which are different not only from static spacetime but also the non-static spacetime described by advanced-Eddington coordinate \(v\) have been chosen. Under the condition that the effect of Hawking evaporation is considered, the temperature of the black hole and the location of the horizon are given. The results indicate that the Hawking radiation temperature can be regarded as a compensating effect under the time-scale transformation.
