Galactic abundances of key elements used to validate our baseline model of the Milky Way, plotted with observational abundance data from NuPyCEE’s STELLAB module, where available (all but [P/Fe]; [P/Fe] abundance data are taken from Roederer et al. 2014; Maas et al. 2019, 2022; Nandakumar et al. 2022). The bulk galactic properties and elemental abundances for most key elements are satisfactorily reproduced. Notable exceptions such as K and Sc have been long established as problematic elements for contemporary stellar evolution and GCE codes (see, for example, Kobayashi et al. 2020).
