Non-Extreme Black Holes from Non-Extreme Intersecting M-branes

We present non-extreme generalisations of intersecting p-brane solutions of eleven-dimensional supergravity which upon toroidal compactification reduce to non-extreme static black holes in dimensions D = 4, D = 5 and 6 ≤ D ≤ 9, parameterized by four, three and two charges, respectively. The D = 4 black holes are obtained either from a non-extreme configuration of three intersecting five-branes with a boost along the common string or from non-extreme intersecting system of two two-branes and two five-branes. The D = 5 black holes arise from three intersecting two-branes or from a system of intersecting two-brane and five-brane with a boost along the common string. Five-brane and two-brane with a boost along one direction reduce to black holes in D = 6 and D = 9, respectively, while D = 7 black hole can be interpreted in terms of non-extreme configuration of two intersecting two-branes. We discuss the expressions for the corresponding masses and entropies. 04.50.+h,04.20.Jb,04.70.Bw,11.25.Mj Typeset using REVTEX On sabbatic leave from University of Pennsylvania.
