Abstract
Abstract Ages, metallicities, and Galactic orbit parameters are considered for those stars with Henry Draper catalog designations that have been discovered to host planetary systems. There are quite a few such stars with above-solar metallicity and ages up to 4 Gyr older than the Sun. Some planet-hosting stars have Galactic orbits that take them within 4 kpc of the Galactic Center, while a substantial fraction attain displacements from the Galactic mid-plane consistent with the thick disk.
