The decay of nonhierarchical few-body systems (N<10) is examined by direct numerical integration to determine statistically how size, shape, N, and rotation state influence the distribution of escape speeds for ejected stars. The initial conditions are chosen to represent realistic configurations for young stellar objects at the end of the accretion phase in fragmented protostellar clouds. If we adopt typical properties for molecular cloud cores and assume system sizes deduced from isothermal collapse calculations, we find that more than 60% of the escapers have speeds >3km/s. We propose that high-velocity stars produced during the decay of young multiple star systems contribute significantly to the halo of weak-line T Tauri stars recently discovered around star forming regions by the ROSAT all-sky X-ray survey.
