Title: Hawking radiation from the Garfinkle-Horowitz-Strominger black hole, effective action, and covariant boundary condition

We exploit the expression for the anomalous (chiral) effective action to obtain the Hawking radiation from a Garfinkle-Horowitz-Strominger (stringy) black hole falling in the class of the most general spherically symmetric black holes ({radical}(-g){ne}1), using only covariant boundary conditions at the event horizon. The connection between the anomalous and the normal energy-momentum tensors is also established from the effective action approach.
