DA white dwarfs from the Palomar Green Survey

DOI

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 (1986, Cat. ). Fits of observed Balmer lines to synthetic spectra calculated from pure-hydrogen model atmospheres were used to obtain robust values of T_eff_, log(g), masses, radii, and cooling ages. The luminosity function of the sample, weighted by 1/V_max_, was obtained and compared with other determinations.
