Abstract
We numerically analyze the evolution of a two-dimensional dilatonic black hole, within the Callan-Giddings-Harvey-Strominger model. We focus our attention on the finite-mass corrections to the universal evaporation rate which applies at the large-mass limit. Our numerical results confirm a previous theoretical prediction for the first-order () correction. In addition, our results strongly suggest that the next-order () term vanishes and provide a rough estimate for the third-order term.

This set-up of semiclassical initial data is described in detail in Ref. [4].
This is the traditional definition of the Bondi mass. In Ref. [10], new definitions were introduced for both the outflux and the “Bondi mass.” These new definitions admit some elegant properties. Here, we prefer to use the traditional definitions for the outflux and , because these traditional definitions make use only of the local geometric (and dilatonic) behavior at FNI (whereas the definitions introduced in Ref. [10] also resort to the time-translation coordinate at left-PNI).
