dc.description.abstractWe use the Sloan Digital Sky Survey Data Release 12, which is the largest availablewhite dwarf catalogue to date, to study the evolution of the kinematical properties of the pop-ulation of white dwarfs of the Galactic disk. We derive masses, ages, photometric distances andradial velocities for all white dwarfs with hydrogen-rich atmospheres. For those stars for whichproper motions from the USNO-B1 catalogue are available, the three-dimensional componentsof the velocity are obtained. This subset of the original sample comprises 20,247 stars, makingit the largest sample of white dwarfs with measured three-dimensional velocities. The volumeprobed by our sample is large, allowing us to obtain relevant kinematical information. In partic-ular, our sample extends from a Galactocentric radial distanceRG=7.8 to 9.3 kpc, and verticaldistances from the Galactic plane ranging fromZ=+0.5to–0.5kpc.
