We examine the injection of short-lived radioactive nuclides into the collapsing presolar nebula. The source of the nuclides is assumed to be the same star that instigated the collapse of the molecular cloud core. Using hydrodynamic models of triggered collapse, we employ two numerical techniques (tracer particles and a color concentration equation similar to the continuity equation) to follow the trajectories of particles carried along by the stellar outflow. The techniques yield the same overall results--roughly 20% of the particles incident on the molecular cloud core are captured by the collapsing protostar in the standard model. This percentage varies with the momentum of the incident material. The injected particles enter the collapsed cloud core in a fairly steady stream, over a time period of approximately 500,000 years.
