Abstract
Through Kepler and K2 observations of evolved planet hosts, we hope to resolve the "Retired A Star problem". Why do evolved stars show a different exoplanet host mass distribution to dwarfs? A selection bias, have the stellar masses for evolved stars derived from stellar models been overestimated, or do they represent a separate population of exoplanets. Asteroseismic observations of 5 evolved stars are presented, where we also incorporate the recent Gaia DR1 parallaxes to address the problem
