Rotating acoustic metrics may have black holes inside the ergosphere. Simple cases of acoustic black holes were studied in the references [21], [4]. In the present paper we study the Hawking radiation for more complicated cases of acoustic black holes including black holes that have corner points.

The Gravitational Bending of Acoustic Schwarzschild Black Hole
Acoustic black hole is becoming an attractive topic in recent years, for it open-up new direction for experimental explorations of black holes. In this work, the gravitational bending of acoustic
Acoustic black hole in Schwarzschild spacetime: Quasinormal modes, analogous Hawking radiation, and shadows
Various properties of acoustic black holes constructed in Minkowski spacetime have been widely studied in the past decades. And the acoustic black holes in general spacetime were proposed recently.

Hawking radiation from not-extremal and extremal Reissner-Nordstrom black holes
We consider the non-extremal Reissner-Nordstrom black hole and construct a wave packet that exhibits the Hawking radiation. We find the average of the number of the created particles with respect to

We study the Hawking radiation for the acoustic black hole. In the beginning we follow the outline of T.Jacobson but then we use a different $2+1$ vacuum state similar to the vacuum state constructed
Stationary black hole metrics and inverse problems in two space dimensions
We study the wave equation for a stationary Lorentzian metric in the case of two space dimensions. Assuming that the metric has a singularity of the appropriate form, surrounded by an ergosphere
Experimental black hole evaporation
It is shown that the same arguments which lead to black-hole evaporation also predict that a thermal spectrum of sound waves should be given out from the sonic horizon in transsonic fluid flow.
On the derivation of Hawking radiation associated with the formation of a black hole
We show how in gravitational collapse the Hawking radiation at large times is precisely related to a scaling limit on the sphere where the star radius crosses the Schwarzschild radius (as long as the
Particle creation by loop black holes
We study the black hole particle production in a regular spacetime metric obtained in a minisuperspace approach to loop quantum gravity. In different previous papers the static solution was obtained
Notes on black-hole evaporation
This paper examines various aspects of black-hole evaporation. A two-dimensional model is investigated where it is shown that using fermion-boson cancellation on the stress-energy tensor reduces the
Black Hole Evaporation
The late stages of black hole evaporation are modelled by processes in which 2 gravitons ! 2 gravitons, with black hole formation and evaporation. The classical analogue of this process is discussed.
