Kinematics of YY Hya based on our spectroscopic system velocity and the Gaia parallax and proper motions. Upper panels: predicted orbit of YY Hya in the Milky Way for the next 2 Gyrs. Left: orbit projected on the Galactic plane, the Galactic center is at the origin. Right: meridional plot of the orbit. Lower panels: comparison of kinematic properties of YY Hya with the local WD sample by Pauli et al. (2006). Left: radial velocity component, U, versus the velocity, V, in rotational direction, the inner circle encloses the region of thin disk objects, the outer circle the thick disk regime. Right: angular momentum component, J_z, perpendicular to the plane versus the orbit eccentricity, e.
