Abstract:
We construct generating solutions for general D-dimensional (4D94 \le D \le 9) rotating, electrically charged, black holes in the effective action of toroidally compactified heterotic (or Type IIA) string. The generating solution is parameterized by the ADM mass, two electric charges and [D12][{D-1}\over 2] angular momenta (as well as the asymptotic values of one toroidal modulus and the dilaton field). For D6D \ge 6, those are generating solutions for {\it general} black holes in toroidally compactified heterotic (or type IIA) string. Since in the BPS-limit (extreme limit) these solutions have singular horizons or naked singularities, we address the near extreme solutions with all the angular momenta small enough. In this limit, the thermodynamic entropy can be cast in a suggestive form, which has a qualitative interpretation as microscopic entropy of (near)-BPS-saturated charged string states of toroidally compactified heterotic string, whose target-space angular momenta are identified as [D12][{{D-1}\over 2}] U(1) left-moving world-sheet currents.
