cds-question@unistra.frwhite-dwarf-starsapparent-magnitudeWe report the spectroscopic identification of close to 1000 hydrogen-rich (DA) white dwarfs discovered in the course of the Anglo-Australian 2dF QSO Redshift Survey (2QZ, Cat. <VII/223>). We measured the atmospheric parameters of a subsample of 201 stars based on good-quality Balmer line spectra and we determine the 2QZ population characteristics. Over ten per cent of the sample are potential ZZ Ceti variables. We estimate the DA white dwarf birthrate (b_DA_=0.5-1.0x10^-12^/yr/pc^3^) and the scale-height (h=220-300pc) of the population in the thin disc of the Galaxy by combining information acquired in the Palomar-Green, AAT-UVX and new 2QZ surveys. White dwarfs appear related to G and late-F progenitors. A catalogue of 201 DA white dwarfs is presented.2002MNRAS.335..673Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/335/673CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/241 : The 2dF QSO Redshift Survey (Croom+ 2004)J/MNRAS/328/805 : 2dF QSO Redshift Survey.
