Scientific paper

We have studied the evolution of r-process elemental abundances in Galactic globular clusters using a simple self-enrichment model. A large scatter in [Ba/Fe] in the globular cluster M15 has been reported. We find that if the r-process occurs in supernovae of low-mass progenitors (e.g., ONeMg supernovae), the observed scatter in [Ba/Fe] can be reproduced while maintaining a uniform [Fe/H] as observed.
