CHARGED STRINGY BLACK-HOLES WITH NON-ABELIAN HAIR

Static spherically symmetric asymptotically flat charged black hole so lutions are constructed within the magnetic SU (3) sector of the four- dimensional heterotic string effective action. They possess non-abelia n hair in addition to the Coulomb magnetic field and are qualitatively similar to the Einstein-Yang-Mills colored SU (3) black holes except for the extremal case. In the extremality limit the horizon shrinks an d the resulting geometry around the origin coincides with that of an e xtremal abelian dilatonic black hole with magnetic charge. Non-abelian hair exhibits then typical sphaleron structure.
