White Dwarfs From the SDSS: 90 Prime - Goin' Deep in the White Dwarf Luminosity Function

Abstract

A large sample of cool white dwarfs from the Sloan Digital Sky Survey has been used to construct a luminosity function (LF), with the selection based on the method of reduced proper motion. While the sample is 60 times larger than that from our Luyten Half Second proper motion survey, its sensitivity to the region past the peak of the LF is severely limited by the necessity to match positions with detections from Palomar plates. A new survey to realize the full limiting magnitudes of the SDSS is described.
