Abstract
For the D-branes on the SL(2,R) WZW model we present a particular choice of outer automorphism for the gluing condition of currents that leads to a special AdS_2 brane configuration. This configuration is shown to be a static solution in the cylindrical coordinates, and a nonstatic solution in the Poincaré coordinates to the nonlinear equation of motion for the Dirac-Born-Infeld action of a D-string. The generalization of it gives a family of nonstatic AdS_2 brane solutions. They are deomonstrated to transform to each other under the isometry group of AdS_3 spacetime.
