Abstract

We consider slightly non-extremal black 3-branes of type IIB supergravity and\nshow that their Bekenstein-Hawking entropy agrees, up to a mysterious factor,\nwith an entropy derived by counting non-BPS excitations of the Dirichlet\n3-brane. These excitations are described in terms of the statistical mechanics\nof a 3+1 dimensional gas of massless open string states. This is essentially\nthe classic problem of blackbody radiation. The blackbody temperature is\nrelated to the temperature of the Hawking radiation. We also construct a\nsolution of type IIB supergravity describing a 3-brane with a finite density of\nlongitudinal momentum. For extremal momentum-carrying 3-branes the horizon area\nvanishes. This is in agreement with the fact that the BPS entropy of the\nmomentum-carrying Dirichlet 3-branes is not an extensive quantity.\n
