What is Hawking temperature

Hawking temperature: The temperature of a black hole is caused by the emission of the hawking radiation. For a black hole with mass m, it is illustrated as:

T = (hbar c3)/(8 pi G k m).

As blackbody power emission is proportional to the region of the hole and the fourth power of its thermodynamic temperature, the emitted power scales as m-2 – i.e., as the inverse square of mass.
