Best-fitting stellar population maps for NGC 3351. The top left panel shows the age map, with a clearly visible nuclear star-forming ring characterized by the presence of young stellar populations. In the top right panel, the total metallicity map of NGC 3351 shows the metal enrichment of both the nuclear disk and the bar. Regions of apparently low metallicity are visible across the star-forming ring. The [Mg/Fe] map (bottom left) exhibits a behavior similar (but inverted) to the metallicity map, with the nuclear disk and the bar appearing as low [Mg/Fe] components. Finally, the bottom right panel shows the IMF slope map where the typical values are close to what is observed in the Milky Way (Γ = 1.3). IMF variations, although mild, partially track changes in both metallicity and stellar density. For reference, a horizontal white line of 10″ or 0.5 kpc at the distance of NGC 3351 is shown in each panel.
