J/A+A/505/441       UVES/VLT spectra of white dwarfs         (Koester+, 2009)

High-resolution UVES/VLT spectra of white dwarfs observed for the ESO SN Ia progenitor survey. III. DA white dwarfs. Koester D., Voss B., Napiwotzki R., Christlieb N., Homeier D., Lisker T., Reimers D., Heber U. <Astron. Astrophys., 505, 441-462 (2009)> =2009A&A...505..441K
ADC_Keywords: Stars, white dwarf ; Magnitudes ; Effective temperatures Keywords: stars: white dwarfs Abstract: The ESO Supernova Ia Progenitor Survey (SPY) took high-resolution spectra of more than 1000 white dwarfs and pre-white dwarfs. About two thirds of the stars observed are hydrogen-dominated DA white dwarfs. Here we present a catalog and detailed spectroscopic analysis of the DA stars in the SPY. Atmospheric parameters effective temperature and surface gravity are determined for normal DAs. Double-degenerate binaries, DAs with magnetic fields or dM companions, are classified and discussed. Description: The spectra are compared with theoretical model atmospheres using a chi2 fitting technique. File Summary:

Note (1): Band as follows: V = V magnitude from SIMBAD or MCS (McCook & Sion, Cat. III/235) B = either Johnson B magnitude or, in most cases, a photographic magnitude from the MCT (Montreal-Cambridge-Tololo survey, see 1990ApJ...351..271D), HQS, or HES surveys mc = Greenstein multichannel magnitude, obtained from the MCS catalog (McCook&Sion, Cat. III/235) Note (2): Several spectra of the same object.
