UVES/VLT spectra of white dwarfs
Listed in IVOA Registry (Virtual Observatory)
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.
Description
The UVES spectrograph at the ESO VLT is used to obtain high resolution spectra with good S/N. 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 homogeneous 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 Hamburg ESO Quasar Survey (HE, Cat. <J/A+AS/115/235>), Montreal-Cambridge-Tololo Survey (MCT), and Edinburgh-Cape Survey (EC, Cat. <J/MNRAS/287/867>) 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.
