Title: Clusters with : systematics from membership and binarity

Abstract: The repurposed {it Kepler} mission, ktwo, has the potential to significantly improve our understanding of how exoplanets evolve. Exoplanets discovered by ktwo can be compared across clusters with a range of ages (10 Myr -- 5 Gyr) to investigate how planet properties change with age and environment. However, this requires an accurate understanding of not just the exoplanet host stars, but the parent sample of cluster candidates observed by ktwo. Poorly constrained membership lists for the cool stars and uncertain binary rates for target stars could lead to systematic errors in our understanding of the intrinsic planet population. Here we propose to continue our RV measurements for a sample of ktwo cluster targets using Hydra on WIYN. With this information we can detect the majority of binaries and remove interlopers from the cluster membership lists. These data are essential to maximize the scientific utility of results from ktwo cluster observations.
