Title: Exoplanet Host Star Age Inferences and Their Impacts on Models of Planet Formation and Evolution

Abstract: Precise stellar ages have among their many uses the potential to reveal the origin, evolution, and fate of exoplanets. While there are many ways to infer the ages of individual isolated field stars, many of these techniques either fail or permit only imprecise model-dependent age inferences for most planet host stars. I’ll describe how Galactic kinematics can provide precise model-independent relative ages for exoplanet hosts and highlight the impacts those relative ages have had on our understanding of planet formation and evolution. I’ll conclude by outlining the future of exoplanet host star age inferences in the age of Gaia and TESS.
