Properties of black holes in toroidally compactified string theory

We review the macroscopic and microscopic properties of black holes of toroidally compactified heterotic and Type II string theory in dimensions 4 less than or equal to D less than or equal to 9. General charged rotating black hole solutions are obtained by acting on a generating solution with classical duality symmetries. In D = 4, D = 5 and 6 less than or equal to D less than or equal to 9, the generating solution for both toroidally compactified Type II and heterotic strings is specified by the ADM mass, [D-1/2]-angular momentum components and five, three and two charges, respectively. We give the Bekenstein-Hawking entropy for these solutions, address the BPS-saturated limit and compare the results to calculations of the microscopic entropy both in the NS-NS sector and the R-R sector of the theory. We also interpret such black hole solutions as dimensionally reduced intersecting p-branes of M-theory.
