[Sc/Fe] vs. [Fe/H] for stars in the solar neighborhood (disks) and Galactic center (triangles), colored by their effective temperature. Shown also are the scandium abundances derived from local disk giants from Lomaeva (Lomaeva 2018) as black dots and the scandium abundances derived from disk dwarfs by Battistini & Bensby (2015) as gray dots. Note how the derived [Sc/Fe] abundance ratio increases drastically as the stars becomes cooler, while the stars near 4000 K and above are more in agreement with both Lomaeva (Lomaeva 2018) and Battistini & Bensby (2015).
