Correction to Hawking Radiation Characteristics of Stationary Demianski-Newman Black Hole

Abstract The pure thermal spectrum in dragging coordinate system and the tunneling radiation characteristics acrossthe event horizon for stationary Demianski-Newman black hole are researched.The result shows that the tunneling rateof the particle is relevant to Bekenstein-Hawking entropy,and the derived radiate spectrum is not strictly pure thermal,but is consistent with underlying unitary theory.Finally,we use the obtained results to reduce to stationary Kerrblack hole and static Schwarzschild black hole,and find that only when ignoring the spectrum at higher energies is thetunneling radiation spectrum consistent with Hawking pure thermal one.
