Abstract :
We show that the most general stationary electrically charged black-hole solutions of the heterotic string compactified on a (10 - D)-torus (where D > 3) can be obtained by using the solution generating transformations of Sen acting on the Myers and Perry metric. The conserved charges labeling these black-hole solutions are the mass, the angular momentum in all allowed commuting planes, and 36 − 2D electric charges. General properties of these black-holes are also studied.
