The properties of exoplanet systems are both observed and theoretically suggested to strongly depend on the mass, metallicity, and evolutionary state of their host stars. One example is that evolved stars do not host hot Jupiters. Tidal evolution is one possible explanation, though the possibility that the evolved stars are more massive than the FG-type stars that dominate the main-sequence sample complicates the interpretation. However, I'll show that the Galactic space motions of the evolved host stars demand that on average they be similar in mass to main-sequence FG type planet-hosts. The two samples therefore differ only in age, and provide a glimpse of the same exoplanet population both before and after tidal evolution.
