Phys. Rev. D 55, 809–813 (1997)Stress-energy tensor of an electromagnetic field in Schwarzschild spacetimeReceived 28 June 1996; published in the issue dated 15 January 1997 The approximate stress tensors of an electromagnetic field in the Unruh and Hartle-Hawking vacua in the Schwarzschild spacetime are constructed. It is shown that by solving the conservation equation in conformal space and utilizing the regularity conditions in a physical metric one obtains the stress tensors that are in excellent agreement with the exact numerical calculations. © 1997 The American Physical Society URL:
