We explore the relationships between the chemistry, ages, and locations ofstars in the Galaxy using asteroseismic data from the K2 mission andspectroscopic data from the Apache Point Galactic Evolution Experiment survey.Previous studies have used giant stars in the Kepler field to map therelationship between the chemical composition and the ages of stars at thesolar circle. Consistent with prior work, we find that stars with high[Alpha/Fe] have distinct, older ages in comparison to stars with low[Alpha/Fe]. We provide age estimates for red giant branch (RGB) stars in theKepler field, which support and build upon previous age estimates by takinginto account the effect of alpha-enrichment on opacity. Including this effectfor [Alpha/Fe]-rich stars results in up to 10% older ages for low-mass starsrelative to corrected solar mixture calculations. This is a significant effectthat Galactic archaeology studies should take into account. Looking beyond theKepler field, we estimate ages for 735 red giant branch stars from the K2mission, mapping age trends as a function of the line of sight. We find thatthe age distributions for low- and high-[Alpha/Fe] stars converge withincreasing distance from the Galactic plane, in agreement with suggestions fromearlier work. We find that K2 stars with high [Alpha/Fe] appear to be youngerthan their counterparts in the Kepler field, overlapping more significantlywith a similarly aged low-[Alpha/Fe] population. This observation may suggestthat star formation or radial migration proceeds unevenly in the Galaxy.
