The Data For Spatial Variations of Stellar Elemental Abundances in FIRE Simulations of Milky Way-Mass Galaxies: Patterns Today Mostly Reflect Those at Formation

Spatial patterns of stellar elemental abundances encode rich information about a galaxy’s formationhistory. We analyze the radial, vertical, and azimuthal variations of metals in stars, both today and atformation, in the FIRE-2 cosmological simulations of Milky Way-mass galaxies, and we comparewith the Milky Way. Overall, spatial variations of stellar metallicities show only modest differences between formation and today; spatial variations today primarily reflect the conditions of stars at birth, with spatial redistribution of stars after birth contributing secondarily.
