Studying r-process mixing in the Early Universe

The rapid neutron capture process (r-process) is responsible for the production of about half the elements heavier than iron. However, the astrophysical site of r-process production still remains a highly debated topic. Observations of metal poor stars indicate that r-process elements were not well mixed in the Early Universe. Recent observations of the r-process abundance spreads of the stars in the Globular Cluster M15 provide further evidence that metal inhomogeneities persist even on relatively small length scales. Motivated by this I have carried out hydrodynamical simulations of galaxy patches to study how the mixing of elements from rare explosive events are imprinted on the abundance spread of those elements in the interstellar medium gas on size scales that are comparable to those of Globular Clusters.
