| Abstract: |
We compare two white dwarf survey populations. A recent all-sky, distance-limited population of nearby white dwarfs extending to 25 pc that contains 232 members, and a large magnitude-limited spectroscopic population, the SDSS DR7 survey, which contains over 20 000 DA stars. We derive distances and interstellar reddening estimates for the DR7 DA stars and compute luminosities and ages. Various aspects of the two samples are compared, including mass distributions, luminosity distributions, and cooling age distributions. |
