| Abstract: |
Using a sample of Galactic halo stars, we will investigate two distinct Galactic halo populations separated by [α/Fe]. The low-α population may be the result of accretion from a dwarf galaxy. Some dwarf galaxies show the signature of asymptotic giant branch (AGB) nucleosynthesis through their neutron-capture element abundance distribution. AGB stars are a known site for the production of heavy elements via the slow neutron-capture process (the s-process). We aim to calculate yields of s-process elements from AGB models. These yields will be used as input into a chemical evolution model for comparison to the high-resolution Magellan data obtained for this investigation. |
