Query: New Supergravity Solutions for Branes in AdS_3 x S^3   We find explicit supergravity solutions which describe branes in the AdS_3 x
S^3 background. These solutions preserve 8 of the 16 supersymmetries of this
background, and are consistent with kappa-symmetry. These represent new 1/2-BPS
states of string theory.
