Abstract
We have started a large survey for radial velocity
variations in white dwarfs (PI R. Napiwotzki) with the aim of finding
close double degenerates, which could be precursor systems for
SNe Ia. The UVES spectrograph at the ESO VLT is used to obtain high
resolution spectra with good 
. During this project 1500 white
dwarfs will be observed. This unique data set will also allow to
derive atmospheric parameters and masses for the largest sample of
white dwarfs ever analyzed in a homogenous way. In this paper we
present a catalog of objects and report results for the first sample
of about 200 white dwarfs, many of which are spectroscopic
confirmations of candidates from the HE, MCT, and EC surveys. Among
the peculiar spectra we identify two new magnetic DA, one previously
known magnetic DA, several DA with emission cores, in some cases due
to a late-type companion, and two new DBA.
Key words: stars: white dwarfs / stars: supernovae: general
Based on observations obtained at the Paranal Observatory of the European Southern Observatory for program 165.H-0588.
