The chemical profile of the star reflects the intrinsic composition of the gas cloud present at its birth. Using an abundance decomposition method, we fit 25 elements from the abundance dataset, including 10 heavy neutron capture elements. We explore the astrophysical origin of the elements in this star through its abundance ratios and component ratios.
