The White Dwarf Luminosity Function: The Shape of Things to Come
T. von Hippel, M. Kilic, J. Munn +10
We describe a new survey for cool white dwarfs that supplements Sloan Digital Sky Survey photometry with USNO proper motions and follow-up spectroscopy. To date we have discovered…
Spectroscopic Identification of Faint White Dwarf Candidates in the Praesepe Open Star Cluster
Kurtis A. Williams, Michael Bolte, James Liebert
We present spectroscopic observations of the remaining four candidate white dwarfs in Praesepe. All four candidates are quasars with redshifts between 0.8 and 2.8. One quasar, LB 6…
The Formation Rate, Mass and Luminosity Functions of DA White Dwarfs from the Palomar Green Survey
J. Liebert, P. Bergeron, J. B Holberg
Spectrophotometric observations at high signal-to-noise ratio were obtained of a complete sample of 347 DA white dwarfs from the Palomar Green (PG) Survey. Fits of observed Balmer…
Discovery of New Ultracool White Dwarfs in the Sloan Digital Sky Survey
Evalyn Gates, Geza Gyuk, Hugh C. Harris +14
We report the discovery of five very cool white dwarfs in the Sloan Digital Sky Survey (SDSS). Four are ultracool, exhibiting strong collision induced absorption (CIA) from molecul…
A Helium White Dwarf of Extremely Low Mass
James Liebert, P. Bergeron, Daniel Eisenstein +4
We analyze the spectrum of an unusually-low mass white dwarf, SDSSJ123410.37-022802.9 (0335-264-52000), found in our recent, white dwarf catalog from the SDSS DR1 data release. Two…
A Catalog of Spectroscopically Identified White Dwarf Stars in the First Data Release of the Sloan Digital Sky Survey
S. J. Kleinman, Hugh C. Harris, Daniel J. Eisenstein +23
We present the full spectroscopic white dwarf and hot subdwarf sample from the SDSS first data release, DR1. We find 2551 white dwarf stars of various types, 240 hot subdwarf stars…
