Meteorite inclusions show that the early solar system was radioactive with species of short lifetimes compared to the formation time of the solar system. Transporting the radioactive material from the creation site to the formation site of the sun was expected to take enough time that these species should have decayed to nonexistence. Some special series of events seems necessary to speed the process along. Cameron & Truran (1977) suggested that the source of these short- lived radionuclides could have been a supernova. Numerical hydrodynamic studies have shown that slow shockwaves can inject material into a small, dense cloud core. Most stars are not born in lone dense cores. Thus any core that might have become the solar system was probably shrouded with an envelope that the ejecta from supernova would have had to penetrate along with the intervening interstellar medium. We present numerical hydrodynamic studies using Zeus-2D that demonstrate the proof of concept that supernova shockwave can carry ejecta into a presolar cloud and make it available to the presolar core.
