Recent isotopic analysis of chondrites shows evidence for live 60Fe in the early Solar System. Only supernovae can produce this short-lived radionuclide, indicating that our Solar System formed in such proximity. Observations of the Orion Nebula, the Eta Carina Nebula and the Eagle Nebula show that young protoplanetary disks, in the stage of forming solids, exist in the vicinity of OB stars. Confirming that our Solar System was subjected to supernova ejecta requires proving that protoplanetary disks can survive the event. A first step has already been carried out by our research group using a two dimensional axisymmetric model. For the following step, we have developed a three dimensional model of protoplanetary disk that allows us to study, as the function of the ejecta incidence and the mass of the disk, the capture of supernova material and the stripping induced by Kelvin-Helmholtz instabilities. I will be presenting that model, the computational implication of such work, as well as preliminary results.
